A healthy baby is the first thing on the parent’s mind and all efforts are done to ensure that the baby gets adequate nutrition. After the birth of the baby, the baby must be fed well either by being breastfed or by formula feeding as per the doctor’s suggestion. Health experts believe that as long as the baby is latching well to the breast and getting fed, the weight gain is consistent, yet it is seen that even after being fed well, some babies do not show a healthy weight gain pattern. So, the concern is “why the baby is not gaining weight”? Who does not want a chubby-looking baby, one who is smiling and roly-poly but if the baby even after being well fed does not show weight gain and is not healthy enough, is it a major cause of concern?

In the article below, we are going to read through a few postulates regarding the same and also understand a few reasons that hinder the healthy weight gain process of the baby.

When Should I Worry About Baby Not Gaining Weight?

Baby not gaining weight is a thing to worry about. It is important to remember that even a healthy baby tends to lose at least 8% or more of their birth weight in the initial days. According to a source, by the time they reach 2 weeks, they should have regained their actual birth weight and after a year, tripled their original birth weight.

Since all babies are different, the weight gain is also different for them. Few have a smaller growth rate than others.

It is suggested by health experts that a breastfed baby should be fed well every 2-3 hours and a formula-fed at a gap of three hours each. Since every child has a specific and unique growth pattern, parents should not compare the two infants born at the same time. Both have different genes and bodies so while one can be chubbier the other can be slightly leaner which should not be a sign of bother for the parents.

Under some conditions though, parents need to worry and consult a health expert and they are:

• In case the baby keeps falling ill often and is very sleepy and cranky
• If the baby is finding it difficult to latch on to the breast and making a sucking noise that is too loud. This happens as they are moving the jaws too quickly and finding it difficult to get milk
• If the mother feels that the breast is not tender enough even after feeding the baby, this shows a sign of the child not getting enough milk. The breast is filled with milk and if the baby latches properly and gets fed, the breasts tend to become softer. On the other hand, if the adequate milk is not taken by the baby, the milk would stay in the breasts making it hard
• If after the regular weighing of the baby, the weight stops increasing after the first three months, it is an indicator of bad nutrition
