Average Weight of 8 Month Old

Height and weight are the most significant indicators of a child’s development up to 12 months. Parents are very concerned about the issue of weight gain. They control the weighing and visit the pediatrician. Appropriate weight control measures are taken where necessary. A diet can be prescribed for its excess and additional nutrition for deficiency.

There are set standards for every age. The weight doesn’t have to match. These are only reference indicators characteristic of most of the children studied. Many babies weigh differently.

Weight standards help parents and pediatricians evaluate the optimal values ​​for a child’s physical development. There are upper and lower limits of normal. The weight of the baby should not go beyond their limits. This state of affairs suggests that the child develops correctly and harmoniously.

The average weight of 8 month old

The most optimal is the average weight. This parameter is 19.6 lb according to the norm for boys of 8 months. The average weight for girls will be 17.8 lb.

8 Month Old Baby Weight

Average weight indicators are established for children born with initially standard body weight. These rules are relative. It is not at all necessary that your baby will weigh exactly as much as indicated in the statistics. There are many cases where children grow on their schedule, with their parameters due to many factors.

Every Baby has Different Weight

Every baby is born with its weight. Babies born prematurely can weigh less than 6.6 lbs and sometimes even less than 4.5 lbs. Their further development is not going according to statistics. They take a long time to gain the missing body weight, so their average values ​​are far from the standards.

A child can be born with excess weight. There are cases when babies weigh 8.8 lb or more at birth. The graph of the ratio of weight and height in this case will be far from standard.

Factors affecting weight

There is no cause for concern as long as the baby’s weight does not go beyond the permissible values. There are a large number of factors on which weight depends. These include heredity, ethnicity, nutritional deficiencies, diet, low mobility, and more.

Any failures in weight should be carefully analyzed by specialists. Identifying the causes can help to quickly eliminate them. Factors that bring down average weight indicators may not be correctable. It’s hard to deal with genetics. You can only limit food a little, reduce the frequency of nightly feedings and add more physical activity.

How Much Boys Weight at 8 month Old

Boys at 8 months old can weigh between 16.3 lb and 23.5 lb. The extreme indicators of these norms will be on the verge of obesity or being underweight. A boy can add 1.1 lb according to statistics by 8 months. A stable tendency to gain weight allows you to keep the norm.


The average weight for an eight month old boy is 19.6 lb. The weight of the child will be close to this norm if he is born of a standard size, there are no problems with health and nutrition. The baby should put on up to 0.7 ounces of extra weight each day. The mass gain in a month will be below or above the established standards if there are reasons for failures.

5th Percentile Weight

The 5th percentile weight for an 8 month old boy is 16.3 lb. This is a lower limit. Weight below this will be considered a disadvantage.

Low weight is not always a problem. It is necessary to be guided by the indicators with which the boy was born and whether there were factors that dramatically changed his weight. Taking into account all the nuances will help to understand whether the current picture is a serious problem. Perhaps this is only a temporary phenomenon that does not require serious intervention.

95th Percentile Weight

The extreme upper point of the allowable weight stops at 23.5 lb. This is the 95th percentile weight beyond which obesity follows. The upper limit of the norm already indicates that the boy is overweight. It is better to take weight loss measures if the trend of strong weight gain continues in the following months.

It is not necessary to immediately put the child on a diet. You can try alternative methods: reducing nighttime feedings, reducing the amount of food at a time, and increasing mobility.

How Much Girls Weight at 8 month Old

An eight-month-old girl can weigh between 14.7 lb and 21.3 lb. The specific body weight will depend on the initial weight, nutrition, and the presence of health problems. How your child will eat will be seen almost immediately. The good appetite of the newborn is most often preserved in the future.


The average weight of an 8 month old girl according to the CDC should be 17.8 lb. This is an idealized figure that should be treated more calmly. It is not required to prudently comply with norms and standards. Your child has the right to weigh slightly less or more than the suggested weight.

Focus on the upper and lower limits of the norms when controlling body weight. They will allow you to avoid mistakes and keep the weight within stable parameters.

5th Percentile Weight

The minimum allowable weight within the normal range is 14.7 lb. This is the line below which there is a strong lack of weight or even exhaustion. It is necessary to immediately seek the help of specialists while maintaining the trend of weight reduction. There is no cause for concern if the girl was originally born with a low weight indicator.

95th Percentile Weight

The extreme upper mark of the allowable weight for an 8 month old girl is 21.3 lb. This is the line that should not be crossed. Obesity follows.

Excess weight is the result of malnutrition. The introduction of complementary foods sometimes provokes a sharp jump in weight. You should first consult with a pediatrician and choose the best complementary foods that are right for your child. Reaching the 95th percentile means it’s time to start thinking about your child’s nutrition.

What is Considered Obesity for 8 month old?


This is the onset of obesity if a girl weighs 22 lb or more at 8 months. This figure is much higher than the mark of the highest weight norm. This situation can become critical. When a baby is fed richly, combining breast milk, formula and complementary foods, the risk of excess weight is significant. It is necessary to balance meals, limiting breastfeeding with complementary foods as much as possible.


Exceeding the 95th percentile weight is a sign of obesity. This limit for 8 month old boys is 23.5 lb. This is obesity if the baby weighs 24 lb or more. It will be accompanied by a constant tendency to exceed the norm weight in one month and the child will begin to get very fat. A boy of this age should gain no more than 1.1 lb per month. The risk of obesity is very high if the numbers are much higher.

The tendency to obesity does not depend on sex and age. It’s more of a genetic factor. It happens that the mistakes of parents who are anxious about weight indicators lead to its strong overabundance. Be more attentive to the child and do not chase the standards.

Signs That Baby is Not Eating Enough

The baby will immediately let you know about it if he is malnourished. The main thing is to be able to notice in time all the signs of being underweight. The main ones are:

  • The child’s weight hardly changes after meals The baby should weigh a little more than before he ate. Check with pediatricians for exact rates.
  • Frequent nocturnal awakenings One or two awakenings per night at 8 months is acceptable. If the child wakes up often, then he is hungry.
  • Too dark and scanty stools The problem is in nutrition if the child poops a little, his stool is very dark in color, and it is more liquid. Food deficiency can cause similar symptoms.

Recommendations for Parents and Their Babies

Always rely on authoritative opinion and information from reliable sources when problems arise. Any recommendation must be justified. An action guide cannot be the advice of a neighbor, mother, or an outsider. You can consult with your doctor in advance, study the information, preventing problems before they arise.

Nutrition and Diet

Make sure there is no excess food. Many mothers continue breastfeeding and additionally give the mixture by introducing complementary foods. Follow the recommendations received if there are good reasons for such a decision.

Try not to feed often at night. Food at this time is digested more slowly and often leads to excess weight. Change the regimen and doses in nutrition before introducing a diet. It is possible to eliminate the problem of increased weight by simpler and non-aggressive methods.


It is necessary to keep a balance between rest and physical activity so that the weight is maintained within the average norms. Teach your child to do morning exercises, massage, and swimming. Do gymnastics and fitball exercises with your baby. Free up space in the room so that the child can crawl on the floor as far as possible. Such a workout burns calories a lot and strengthens the baby’s muscle frame.

Activate the brain

The brain of a child at 8 months is ready for active cognitive activity. Buy educational puzzles, pyramids, and constructors. These will be very simple tasks, but they will give a serious shift in mental development and increase energy costs. Calories are burned much faster with mental work than with physical work.

Dose Communication

Children are all very tempting to a large number of relatives and friends. Everyone wants to come, indulge and babysit the baby. Enter visiting mode. Make it so that the baby does not interfere with the period of eating and sleeping. Count only on the time the child is awake. This will reduce the risk of overexcitation and not knock down rhythms.

Why Your Baby’s Weight is Not Close to Average

Your baby is not obliged to anyone and grows at its own pace laid down by its genetics. Strongly interfering with weight parameters is not worth it if there are no health problems. Average body weight by age is acceptable to fix serious deviations. Minor glitches may occur. There is nothing wrong.

Ethnic features

The statistics on weight norms do not indicate belonging to a particular ethnic group. Some peoples are characterized by fullness. Others are thin and small in stature. Your baby will take this information from the genes and then his height and weight will differ from the average standards.

Poor nutrition

Weight can be much less than normal if the baby is still eating poorly or completely refuses complementary foods. There will be a clear lack of weight with a shortage of milk in the mother. There is an excess of weight and excess of its maximum norms if the child constantly overeats.

Constant sleep problems

Biorhythms go astray when the child does not sleep well during the day, refuses of naps, and reduces the daily rate of sleep. This entails a loss of appetite and failure of the regimen.

Emotional instability

Depletion of the nervous system occurs if the baby is often nervous, scandalous, and freaking out for the slightest reason. The child’s mood changes too often and he cannot fight tantrums because he is still too young. This behavior is bad for health and can bring down average weight indicators.

Lack of physical activity

A child at 8 months masters a huge number of motor skills. He freely turns in any direction, stands at support, sits, and may even try to walk with support. The accumulation of excess weight is observed if the activity of the child is reduced.

Serious illnesses

The risk of being overweight is high in diabetes. The average indicators of the norms are shifting and this will not be considered a pathology. More serious illnesses can cause excessive thinness and an inability to gain weight.

When Should You Worry?

A serious cause for concern should be the continuing trend of increased or greatly reduced weight. When a child gradually but steadily loses weight over several months, this is a reason to undergo an examination. Be especially serious about sudden weight loss in a short period.

There is reason to worry when the baby does not perceive food well. Sometimes children do not digest dairy products or a particular type of puree. The reason may be personal intolerance, allergies, or poor quality of food. Keep track of your child’s stool and urine color. Notice allergic reactions immediately and stop the product being administered. The child should not have vomiting, diarrhea, or severe pain after eating.

Reduced immunity can signal a vitamin deficiency. A constantly ill child should eat fully with the possible introduction of vitamins into the diet.
