Is My Baby Too Skinny, Underweight or Thin? 3 Ways To Know


Becoming a parent is fraught with anxiety, and you may find that you frequently second-guess yourself regarding the well-being and growth of your child after you give birth. Sometimes people you know, people you don’t know, and even strangers will give you their opinions and suggestions, which may cause you to feel uncomfortable and frightened.

The majority of the time, parents are concerned about their child’s weight, specifically whether or not their child is too thin. In Western culture, they often have the picture of a plump, squishy infant covered in rolls entrenched in their brains as the perfect healthy, happy, and well-fed child. This is despite the fact that the ideal healthy, happy, and well-fed child actually looks very different.

However, it is essential to keep in mind that babies, just like adults, can come in a wide variety of shapes and sizes. This article is going to go over the three most important ways to figure out if your kid is too skinny, as well as provide you with some useful suggestions that will hopefully make you feel less stressed.

Is My Infant Not Getting Enough to Eat?

“Have you been feeding her?” “She might benefit from starting solids sooner,” “You really ought to give them formula,” etc.

During the first year of their children’s lives, many parents are likely to have frequently heard one of these comments or a version of them at some point in their children’s lives.

When it comes to their child’s weight, many people have the outmoded attitude that formula and solid foods are the answer, despite the fact that hearing these comments can be just the contrary and a significant setback for the parents.

No matter whether you choose to breastfeed or bottle feed your child, having accurate information is essential to having a healthy child and contented parents.

You will know your child better than anyone else, and you should listen to the words of medical professionals more than you should take the unwanted advice that your aunt gave you while she was visiting.

There are three ways to determine whether or not your baby is too Skinny.


You may detect if your infant is too slender, too thin, or underweight by looking at them in one of these three ways:

1. Charts Depicting Growth

During the checkups that your children needs to have about their weight, the pediatrician will frequently make reference to “the chart.” It’s possible that you’re confused about what this chart is and how accurate it actually is.

These charts, which are determined by the weight of your baby when he or she was born, provide a general roadmap for how your child should develop in order to be considered healthy and free from any cause for concern from a medical professional.

The World Health Organization (WHO) is the organization that compiles these charts for newborns and children aged 0-2 years. The Centers for Disease Control and Prevention (CDC) is the organization that compiles these data for children aged 2 years and above.

During doctor’s appointments, these charts will be used to contribute to a more comprehensive medical picture of your child.

Your infant will have a predetermined line on the chart that, based on their birth weight, will compute their growth throughout time. This set of lines is referred to as the “percentile curves,” and it was created using data from babies who were breastfed as well as newborns who were fed formula.

2. Keeping an eye on the feeds

Many people will tell you that your child does not need to feed more frequently than once every two to three hours and that this is plenty, but the reality is that this could not be further from the truth.

Particularly in the case of babies who are being breastfed, they may frequently want to be latched on quite frequently and for extended amounts of time in order to assist in encouraging your milk supply. It is NOT a sign that you do not have enough milk if you are feeding yourself frequently.

Having a medical professional or an IBCLC (International board-certified lactation consultant) assess your latch is frequently the salvation for many women’s breastfeeding adventures. This can help to provide helpful information and guidance on normal feeding patterns and hunger cues for your baby.

Your newborn will drink between 1.5 and 3 ounces of milk every two to three hours, regardless of whether or not they are being bottle-fed. This does not, however, imply that they will function like a well-oiled machine; rather, they may at times demand more or less depending on a number of circumstances like growth spurts and gas.

At about 2 months old, your baby should be taking approximately 4-5 ounces at each feeding, which should occur approximately every 3-4 hours.

You should follow the instructions on the formula powder boxes, which are organized according to age, to make sure that your bottles are properly made and contain the appropriate amount of nutrients for their age range.

3. Diapers

The amount of waste produced by your child’s diaper is yet another excellent indicator of whether or not they are getting enough to eat. As a general rule of thumb to determine whether or not your infant is getting enough to eat, you can look at the amount of wet and dirty diapers they produce.

As a warning indication of dehydration in your infant, your child should never have fewer than six wet diapers in a period of twenty-four hours, and they should never go more than two to three hours between wetting their diaper.

It is important to keep in mind that if you suspect that your infant is dehydrated, you should always seek the counsel of your paediatrician or the doctor’s office. If not addressed, this condition can lead to significant complications.

Under the age of one, your child should have anywhere from one to three bowel movements every day, and possibly even more if they are breastfed. This is a general rule of thumb. The uniformity and hue are frequently used as indicators of potential problems.

  • Babies who are fed formula typically have a dark green stool.
  • White — Possibly an indication of liver problems
  • If your skin is black, it may be a symptom that you are not getting enough nutrients.
  • Red – Calm down, this could be blood if you are nursing and are experiencing constipation, strain, or broken nipples.
  • Yellowish-brown — the standard!
  • Teething is one of the possible causes of this bluish-greenish colour.

Symptoms of a Baby Who Is Underfed

Many times, the warning signals that your infant is not getting enough food or is too thin are pretty evident, and parents are able to recognize them quite quickly.

If your child is not getting enough to eat, they will likely not hit developmental milestones at the appropriate ages, as well as become irritable and inactive, have trouble sleeping, and frequently fall asleep before they are able to finish a feed.

Infrequent defecation in infants can be considered normal; nevertheless, if you discover that your child is also fitting some of the other criteria that we have just given, you should seek the opinion of a medical professional just to be on the safe side. The following are additional signs:

  • Fewer than four soiled diapers
  • Constant fussing
  • Having difficulty waking up

Frequency Asked Questions

How can I get my child to stop being so skinny?

Avoid giving your child any artificial sweeteners or sweets and instead choose foods high in healthy fats like nut butter, avocados, and fish if they are beyond the age of six months and you are beginning the process of weaning them off of breast milk or formula.

Is it unhealthy for a baby to have a low body fat percentage?

Some infants are said to be “genetically lean,” which means that due to their genetics, they will appear to have less body fat. However, this does not indicate that the infants are underweight or that they are not receiving adequate nutrition.

What should I do if I have to leave my baby without a feeding?

Don’t worry; in most cases, your child will let you know as soon as they are hungry again, even if they are busy doing something else, and everything will go back to normal. If your child is sleeping or engaged in another activity, try not to worry.

Final Thoughts

Babies more often than not have a valid explanation for their decreased feeding and apparent unhappiness; nevertheless, they are unable to articulate their needs. The only way that a baby can communicate with you when anything is wrong is through their cries.

Whether it be a soiled diaper, gas, or hunger, it might be difficult to discern what your little one needs at times; however, this can become better, and it does not necessarily mean that they are underfed.

Keep in mind that just because a newborn is underweight, it does not necessarily mean that they are not getting enough to eat; genetics can play a significant role in how they develop.
