The most RAPID period of growth is between 2 weeks and 6 months of age. Monitoring your baby's growth. AVERAGE WEEKLY FIGURES; which offers a quick guide, depicting a range of weekly growth for babies at different ages. Your health care provider will use growth charts to monitor and record your baby\'s WEIGHT, as well as her LENGTH and HEAD CIRCUMFERENCE. Growth charts are an important tool for monitoring children\'s development, but they are just one of the tools your health care provider will use to ensure your baby is growing and developing as she should. If you do NOT have one of these booklets you can download copies of different growth charts from the National Center for Health Statistics and maintain your own records. Growth charts provide a MORE reliable tool for assessment of your baby\'s pattern of growth than \'average weekly figures\' (described below). You can use growth charts to COMPARE your baby\'s weight with her length, which can provide a guide for REALISTIC expectations of weight for individual babies. Some health care providers will compare your baby\'s weight gain against \'average weekly figures\' in order to monitor growth between developmental checks at well baby visits. \'Average weekly figures\' provide the range of weight which is considered to be of average gain for babies of different ages. Unlike growth charts, these figures do NOT accommodate variations between boys and girls. IMPORTANT: Whether you use average weekly figures or growth charts, REMEMBER these provide a GUIDE ONLY. Even without weighing your baby YOU can tell when she\'s gaining weight, particularly when she\'s a very young baby and growth is at it\'s most rapid.

Ideal Weight Gain in a Newborn Baby. Proper weight gain is important to the development of a newborn. A baby who stays within the average weight gain range is generally developing well. The average baby loses about 10 percent of his birth weight in the first five days, according to Health Children.org. By about 10 days old, your baby should be close to his birth weight again. Regardless of birth weight, healthy babies gain weight at about the same rate. The weight gain range for newborns is about 4 to 7 ounces per week for the first month of life, according to the Ask Dr. The specific weight gain varies by baby and may correlate with both the newborn's body type and activity levels. A shorter, rounder baby or one who doesn't move around much doesn't burn as many calories and may gain weight faster.
A 5-7% weight loss during the first 3-4 days after birth is normal. Baby should regain birth weight by 10 days to 2 weeks. If your baby lost a good bit of weight in the early days, or if your baby is sick or premature, it may take longer to regain birth weight. If baby does not regain birth weight by two weeks, this is a sign that the breastfeeding needs to be evaluated.
Your Newborn's Weight: What's Normal, What's Not. At birth, the average baby weighs about 7.5 pounds — though the range of normal is between 5.5 and ten pounds (all but five percent of newborns will fall into this range). What makes your baby weigh more or less than the newborn in the next bassinet? Your own diet and weight, both before and during pregnancy (If you’re overweight, you may have a heavier baby. If you don’t get enough nutrients while you’re pregnant, your baby may be smaller.) Your own birth weight, plus genetics (your size at birth, plus your and your hubby’s size now, can both play a role) Whether your baby is a boy or a girl (boys tend to be heavier) Whether your baby is a twin or triplet (multiples tend to be smaller than singletons) Don’t be alarmed to learn that, upon discharge from the hospital or birthing center, your baby will weigh on average five to ten percent less than she did at birth. (If your practitioner schedules fewer appointments, feel free to bring your baby in for a weight check anytime.) Plus, many nursing and new-mommy support groups have baby scales so you can get a quick read. Another good gauge: If your baby is eating enough, she’ll produce eight to ten wet diapers a day, and at least five poopy ones if she’s breastfed (fewer for formula-fed newborns). (It’s a good thing that breastfeeding is all about supply and demand; the more baby nurses, the more milk Mommy makes!)
The Average Weight Gain Per Month for Newborn Babies. Also, intravenous fluids used in labor can transfer to the unborn baby, which is one potential cause for a newborn baby's weight being higher at birth than a few days after birth. It's normal for a formula-fed newborn to briefly lose about 5 percent of his birth weight, while a breastfed infant may temporarily lose from 7 to 10 percent, explains the American Pregnancy Association. Premature or sick newborns may lose more weight after birth, and it may take as long as 3 weeks for the newborn to gain back the weight. Between 1 to 4 months of age, an infant will generally gain 1 1/2 to 2 pounds per month, explains Healthy Children.org, the website published by the American Academy of Pediatrics. From 4 to 7 months, his weight gain will slow to 1 to 1 1/2 pounds each month. Around 4 months, breastfed babies will begin to look chubbier than formula-fed babies, according to the AAP. The rapid growth that occurred during the first year of life slows when a baby becomes a toddler. A 3-to-5 pound weight gain is about all you can expect during the entire second year.
POOR WEIGHT GAIN OVERVIEW. HOW IS POOR WEIGHT GAIN DEFINED? Poor weight gain is defined as gaining weight at a slower rate than other children who are the same age and sex. However, some children do not gain weight normally from birth, while other children gain weight normally for a while, then slow or stop gaining weight. A child is said to have poor weight gain if he or she does not grow at the expected rate for their age and sex. POOR WEIGHT GAIN CAUSES. The causes of poor weight gain include the following: Common causes of poor weight gain for each age group are described below:
How much weight should my baby gain each month? Q: How much weight should my baby gain each month? 1 to 4 months: Babies usually gain 1 1/2 to 2 pounds and grow 1 to 1 1/2 inches each month. By 6 months: Most babies have doubled their birth weight. By 12 months: Most babies have usually tripled their birth weight and will have grown 9 to 11 inches from their original birth length. By 24 months: Most babies have quadrupled their birth weight and will have grown 14 to 16 inches from their birth length.
Birth weight and gestational age. Small for gestational age (SGA) babies are those whose birth weight lies below the 10th percentile for that gestational age. One third of babies born with a low birth weight are also small for gestational age. Measurements can be taken of the fetus' head and limbs and compared with a growth chart to estimate fetal weight. The main causes for Low Birth Weight: The two main causes of LBW are early delivery, also known as preterm birth, and poor fetal growth. The remaining 30% of low birth weight babies are born at full term, but did not grow properly in the womb. ~ Some of the risk factors for preterm birth are: Fortunately, there are things that can be done to prevent some low birth weight babies. High birth weight (HBW), babies weighing over about 9 pounds (4,080g) fall into the 90th percentile for weight and are known as large for gestational age (LGA) babies. There can be a difference of 10-15 per cent between the weight predicted by ultrasound and the actual weight of the baby at birth, especially if you are close to your due date. Much of the birth weight variation remains unexplained, and most macrosomic infants do not have identifiable risk factors. And women who are being treated for gestational diabetes should also strive to keep weight gain below 40 pounds. Women who eat well and gain the appropriate amount of weight are more likely to have healthy babies.
That’s why it can be worrisome for some moms to see baby “dropping” in the percentiles for weight. It’s not uncommon for a baby who started out in the middle or high end of the weight chart to creep down well below the middle by a three- or six-month doctor’s visit. But one of the reasons this dip in percentiles happens is that many pediatricians use height and weight charts that are based on populations of babies who are fed formula. For example, the CDC produced a growth chart in 2000 that used a population representative of babies in the U. So if your baby’s pediatrician was using this chart, you might find that she drops lower and lower as the months go on, as she’s being compared with a population that is having more and more formula in their diet. The World Health Organization has a set of growth charts that are a more accurate and useful measure of your baby’s height and weight. In fact, just recently, the CDC recommended that all pediatricians use these WHO charts for babies ages 0 to 24 months . The charts are based on a very large international sample of infants who were exclusively breastfed until at least four months and at least partially breastfed for 12 months or more, with no solid foods until six months. All babies look heavier on the WHO chart, and a breastfed baby is more likely to stay on target for weight when being compared with this sample. For more on tracking your baby’s growth, check out the CDC’s full recommendation on height and weight charts.
If the mother has diabetes or is obese, the baby may have a higher birth weight. A poor diet during pregnancy can affect how much a newborn weighs and how the infant grows. Gaining too much weight can increase the likelihood that a baby is born bigger than average. Medical problems, including some birth defects and certain infections acquired during the pregnancy, can affect a child's birth weight and later growth. Many pre-term babies are classified as having "low birth weight" or "very low birth weight." In medical terms, "low birth weight" means a baby weighs less than 5 pounds, 8 ounces (2,500 grams) at birth. Babies are born with some extra fluid, so it is perfectly normal for a newborn to drop a few ounces when that fluid is lost in the first few days of life. Newborns are so small, and it can be hard to know if your baby is gaining weight the way he or she should. You may worry that your baby has lost too much weight in the first few days or isn't taking enough breast milk or formula . A breastfed baby may have only 1 or 2 wet diapers a day until the mother's milk comes in. How many bowel movements your baby has each day, and their volume and consistency. Plenty of towering teenagers began life as small babies, and the biggest baby on the block can grow up to be a petite adult. Genetics, as well as good nutrition and your attention, will play a large part in determining how your baby grows in the years to come.
Average Breastfed Baby Weight Gain. Breastfed Baby Weight Gain. Formula-fed and breastfed baby weight gain will vary because they grow at different rates. Here’s a general guide to the growth and breastfed baby weight gain during the first year: Breastfed baby weight gain (growth patterns) Weight gain of 4-7 ounces (112-200 grams) a week during the first month. Breastfed and formula-fed infants grow at basically the same rate in the first few months. Between four and six months, formula-fed babies tended to gain weight faster than their breastfed baby peers, although growth in length and head circumference were similar in both groups. Monitoring of breastfed baby weight gain vs. Formula-fed baby weight gain during this study indicated that compared to their formula-fed friends, breastfed infants gained an average of one pound less during the first twelve months. Researchers in the study concluded that new standardized growth charts are needed that will reflect the different breastfed baby weight and growth patterns present in healthy, normal breastfed babies. Mellow, laid-back babies tend to burn fewer calories and therefore gain weight more quickly. Breastfed baby weight gain is influenced by frequency of feeding.
WHO 0-2 Years: Weight For Age Percentile. Note, the CDC recommends the use of the WHO charts for babies and infants from birth to two years of age. For example out of a sample of 100 babies, a percentile value of 40 percent means your baby weighs more than 40 babies and weighs less than the other 60 babies. A percentile of 50% represents the average or mean weight. Percentile - The weight percentile of the child. Age - The age of the child in months. "The WHO Child Growth Standards". After two years, it is recommended to return to the CDC charts. CDC Growth Charts: WHO Growth Charts:
A Pediatrician Explains How Much Weight Newborns Gain in the First Two Weeks. Our grandchild went to the doctor this morning for her two-week check up. Four days later (my daughter had a c-section) she left the hospital at six pounds, 11 ounces. At the jaundice check up, she weighed seven pounds, one ounce, and now (at 13 days) she weighs only seven pounds, six ounces and is 19 3/4 inches. The doctor said that everything is normal. Most babies lose weight during the first week and then get back up to their birth weight by the time they are two weeks old. Since your grandchild has not only met her birth weight but is now over her birth weight by two ounces, at day 13, your pediatrician is probably right that she is growing just fine. So if she was seven pounds, one ounce at about six days of life, then she gained five ounces over the next seven days, which is still well within normal expectations. So, at the moment, you likely don't have to worry about your grandchild's weight. The first step would probably be to stop supplementing with formula, since you describe that making her worse, and maybe have mom stop eating and drinking dairy products. This guide to colic in the breastfed baby discusses other problems that might cause a breastfed baby to have watery stools. Since you feel so strongly that something is wrong, you likely should schedule another appointment with the baby's pediatrician for another weight check to make sure that she continues to gain. You might also try to go to this visit with your daughter so that you can express your concerns and get an explanation from the doctor.

Height & Weight Pattern in the Growing Baby. You need to understand the importance of the role of weight gain, and therefore of your baby's expected or ideal weight. The baby's birth weight is the starting point for growth. Whatever be the birth weight, the growth rate in all the babies is approximately the same. Height or length of the baby matters too. Weight gain is not the only way to assess a baby's growth. The baby's length will change much more slowly than the weight. Just as there is expected weight gain for a baby of any age, related to the birth weight, so there is a expected length at any age, related to the birth-length. There is a consistent relationship of weight and height in the normal growth pattern of the child. The weight tends to remain in low position for a long time. Babies who are bottle-fed from birth : These babies may loose no weight in the first days. There is a obvious disparity in the height gain compared to the weight.
Baby Growth Chart: Track Your Baby’s Growth and Development. The centerpiece of your child's health record is the baby growth chart. Your healthcare provider will track your baby's height and weight on a percentile chart such as the ones below. This chart will help you follow your child's growth along with the healthcare provider.
