Average Weight of 5 Month Old

Height and weight are the main indicators of the development of a baby up to 1 year old. These parameters are under the close supervision of pediatricians. Monthly weighing is an integral part of every doctor’s appointment. Weight control allows you to assess the quality of the child’s nutrition. Milk deficiency will directly affect the overall weight gain.

Statistically established average weight norms for 5 months are not a strict standard. Shifts up or down are allowed. The amount of weight gain for each month gradually decreases closer to the year. Now the child should add up to 1.3 lb. Sometimes these numbers are much lower.

Weight control helps to maintain it within the normal range. This is important for the health and general well-being of the baby. Appropriate action is immediately taken in case of deviations.

The average weight of 5 month old baby

The average weight of a five-month-old boy is 16 lb. The figure is slightly lower for girls. By 5 months they weigh an average of 14.7 lb.

5 Month Old Baby Weight

Boys are initially slightly ahead of girls in terms of average weight. The situation may change further. It is not necessary to adjust to weight standards. These are just averages for most children. The main thing is to make sure that the weight does not go beyond the maximum allowable norms.

Every Baby has Different Weight

The doctor can determine whether your baby will be large while still in the womb. Birth weight largely determines the further growth dynamics of the baby. Each child has their weight. It cannot be changed radically. Fighting weight is difficult with a tendency to be overweight, but realistic.

All children are individual. Their development and growth are the information laid down by genetics. Weight can change under the influence of many factors.

Factors affecting weight

Don’t worry ahead of time if your child’s weight doesn’t meet CDC guidelines. The child develops at his own pace. Weight can be determined by heredity, belonging to a particular ethnic group, health status, and nutritional habits.

Make sure that the baby does not weigh much more than the maximum allowed or less than the lowest mark. These boundaries are an acceptable range of body weight. Outside of them are deviations that need to be corrected immediately. All other indicators are acceptable norms. Which shouldn’t bother you.

How Much Boys Weight at 5 month Old

Weight gain at five months of age is up to 1.3 lb. The baby can gain body weight from 13.2 lb to 19.6 lb. Extreme indicators will determine the critical points at which you should think about adjusting nutrition. Anything below the smallest allowable weight will be considered underweight. Anything above is overweight.


Boys gain about 0.7 ounces of extra weight every day from 4 months onwards. The average weight of a five-month-old baby at this rate would be 16 lb. This is a standard indicator based on average birth weight and stable adherence to monthly growth rates.

Of great importance for average weight at this age is the balance between sleep and wakefulness. The baby should be active, sleep well and eat well. Then the weight will be within the normal range.

5th Percentile Weight

The 5th percentile weight for a boy at 5 months is 13.2 lb according to the CDC. Exceeding this limit is not a deviation. There is a lack of mass if this mark is significantly reduced. This situation calls for quick intervention. A mixture is prescribed and work is underway to establish lactation. Nutritional deficiencies have a bad effect on the general well-being of the baby, his appearance, and health.

95th Percentile Weight

A five-month-old boy can weigh much more than the prescribed norm. His 95th percentile weight is 19.6 lb. This mark is already considered overweight. Achieving this parameter indicates that it is time to think about moderate nutrition. There should not be strict restrictions. You can get away with reducing night feedings.

The further situation will depend on the parents. The main thing is not to allow excessive excess of the maximum allowable weight.

How Much Girls Weight at 5 month Old

Girls by standard weigh slightly less than boys. A girl at 5 months weighs from 12.1 lb to 17.8 lb. These are the limits of the norm beyond which there will already be deviations. The weight of a baby of this age is determined by the initial parameters at birth. The loss in the first few days and the further trend of mass gain are taken into account.


Girls, like boys, add about 1.3 lb of extra weight by 5 months. The average mark of this parameter reaches 14.7 lb at this age. Weight can be either lower or higher than the indicated figure. The main thing is that the indicator is within the limits of the maximum allowable values. Weight gain for a month will be reduced gradually.

5th Percentile Weight

The 5th percentile weight of a five-month-old girl is 12.1 lb. This is the limit below which underweight will be diagnosed. This situation indicates the presence of a deficiency of milk in the mother. Being at the lower limit of the norm of permissible weight does not indicate the presence of deviations.

The 5th percentile weight can be slightly larger than the specified parameter. This is quite possible for several reasons: the initial size of the girl, good nutrition, or heredity.

95th Percentile Weight

The upper limit for a girl is 17.8 lb. This 95th percentile weight can already be considered overweight. It is worth thinking about restrained nutrition and reducing the number of feedings at night. They have a bad effect on weight leading to its strong increase.

The 95th percentile weight for a 5 month old girl may have different data. It all depends on the baby’s initial weight, her state of health, genetics, and the balance between nutrition and activity.

What is Considered Obesity for 5 month old?


Anything above the 95th percentile is considered obese for girls. Above the maximum weight limit is 18.2 lb at 5 months according to the CDC. Such a mass will be more than excessive and may indicate the onset of obesity.

You should immediately seek the help of a specialist if you suspect excessively rapid weight gain. Adjusting nutrition is quite simple at the age of up to 1 year. Diet is introduced in extreme cases when other measures do not help.


Since the maximum allowable maximum weight for boys is higher than for girls, completely different norms are considered obesity. The weight of 20.2 lb is already too big for a five month old boy. This is an excess of the 95th percentile weight beyond which obesity occurs.

The regulation of nutrition for children of different sexes is the same. There is no difference in how to adjust the nutrition of boys and girls. The main thing is to return the baby to the frame between the upper and lower weight limits.

Obesity is a serious problem at any age. Solve the issue immediately so as not to start this situation and save the baby from further more serious problems. Timely adjustment of nutrition, adherence to the regimen, maintaining activity, and dieting are the best helpers in the fight against obesity.

Signs That Baby is Not Eating Enough

Nutritional deficiencies are just as dangerous as obesity. You can understand that the baby is malnourished by fairly simple signs. Let’s consider the main ones:

  • Thinness Children at 5 months should be rounded. This is a lack of nutrition if the baby is too thin and small.
  • Rare urinationThe baby should urinate up to 5-7 times a day at 5 months. The baby is most likely not getting enough milk if the diaper is often dry.
  • Frequent awakenings at night A hungry child will not be able to sleep uninterrupted at night. He will constantly wake up and demand breasts or formula.

Recommendations for Parents and Their Babies

Feelings about the weight of the child must be justified. Keep a sober mind to properly solve the problem that arises. Start with yourself. Relax and seek professional help. Only he and reliable sources of information can help with recommendations for restoring weight to the normal limit.

Nutrition and Diet

It is necessary to enter the diet immediately after birth. It is better to feed the baby by the hour. This makes it easier to control the process. Reduce or increase the number of meals and their duration depending on the situation.

Seek help from a lactation specialist if you have lactation problems. The mixture must be introduced very carefully. Start with the smallest doses and immediately observe the baby’s reaction to the composition.


A five-month-old baby rolls over well, begins to speak the first syllables, reaches for toys, and tries to crawl. Lay the baby on his stomach as often as possible to maintain mobility. Teach your baby to crawl. Do not stop massage and gymnastics. The activity of the child will help keep the weight within the normal range. Increase the amount of exercise if there is a risk of obesity.

Don’t skip visits to the pediatrician

A problem that is noticed in time is better solved. You may not notice that your baby is on the verge of obesity or miss the moment of a critical nutritional deficiency. A specialist will help you immediately determine the causes of a particular problem and give all the necessary recommendations.

Your child’s health should always come first. Do not be guided by the opinions of others and it is better to ask a specialist.

Eliminate co-sleeping gradually

Try moving your baby to a separate bed if he sleeps a little better at night. So he will wean from nocturnal awakenings due to the breast. This will reduce the risk of obesity and improve your sleep pattern. A well-rested mother is a holiday in the family. Sound sleep of the baby will improve the schedule and harmonize the balance between sleep and rest.

Why Your Baby’s Weight is Not Close to Average

If the weight of the child does not correspond to the average, this does not mean that there is a problem. Children all grow according to an individual plan laid down by genetics. Many factors affect weight.


A child born before the due date will weigh much less than the accepted norms. He is weaker and recovers for a long period. This brings down the average weight for age.

Lack of a meal plan

The baby begins to eat and sleep spontaneously if the mother does not initially adjust his schedule. Biorhythms get lost and confused about the time of day occurs. The baby suffers from a lack of stability. This greatly affects weight gain.

Not adjusted lactation

The breast of a nursing woman should constantly fill up. The child eats up emptying it. There is a gradual strong shortage of mass if there is a shortage of milk.

Genetic features

Nobody canceled the factor of heredity. Large parents produce large children. The baby has nowhere to get genetic information and a gene of great height and weight if from generation to generation everyone was small and thin.

Permanent static

Active moms often make a big mistakes. They retain their mobility by reducing the activity of the baby. Constant stay in a car seat, crib, stroller, or narrow playpen limits the child’s mobility. This can lead to excess weight.

Health problems

It will be difficult for a child to keep up with weight standards if the child often has problems with the digestive system. Frequent regurgitation, loose stools, colic, and other disorders lead to weight loss.

Constant stress

An unfavorable atmosphere in the family, constant scandals, quarrels, and screams can cause a state of chronic stress in an infant. A mother in depression may forget about the responsibilities of caring for a baby. All this harms weight.

When Should You Worry?

The main cause for concern should be a violation of the health of the child. His well-being will determine whether he has enough milk. Severe deficiency can result in anemia, severe weakness, and pale skin. Visual signs will immediately make it clear that the baby is malnourished.

Severe sleep disturbances on an ongoing basis may indicate nutritional problems. This is not necessarily a lack of milk. Overeating can be the cause of poor sleep. The child will begin to wake up with abdominal pain, strong gas, or problems with the pancreas.

It is necessary to immediately consult a doctor if the baby lags in some indicators of development. Perhaps the reason for this is a lack of nutrients or exhaustion. Call your doctor right away if your baby is spitting up, has loose and frequent stools of an unusual color, or has other signs. Any reason to worry can be justified.
