One of the first things that they do when your baby is born is measure its weight and height.
Your pediatrician will do is every time you go for a regular check.
The growth of the child is pretty much standardized and can usually be predicted with great accuracy.
You can look up these growth charts on the internet but always make sure you check the publication date as they do change from time to time to take up changes in infant healthcare into consideration.
There is no need to obsess over in which percentile your child falls.
It is not because it's in the 50th percentile that it's not healthy, it just means that half of the babies of the same age are larger and the other half on small.
Your child can also be in different percentiles for height and weight.
Don't worry if your baby consistently measures at the lower or higher end of the charts.
The only thing that is really important is that there is a consistency in its growth.
Yet the top-end border bottom means that the child is a bit larger or smaller than their peers.
The only time that pediatrician will take action is if there is a sudden, drastic downward deviation from the curve.
As this might signal that the baby is not thriving.
When examining the size and weight of your baby, the pediatrician will take your own size, and that of her spouse into account a smaller parents tend to have smaller children.
He will also ask you with the babies eating and sleeping sufficiently and if he looks alert when awake.
Breast-fed babies will be more weight in the first three months of their life, while bottle-fed infants who gain more in the second half of the first year.
There is no reason to change feeding habits sooner, like putting the baby on solid food, because of this as long as the baby grows consistently.
