Welcome to Just Answer!
Thanks for posting your query.
I am Dr.Ratnakar and I am pleased to assist you.
If you have questions after reading my answer, be sure to let me know.

Your nephew's weight is ok for his age only.
It is above the 50th percentile.

We also use a simple calculation (age in years X 2) + 8.
So for a 4 year old boy, the weight should be 16 kg.
Your nephew's weight is almost normal for his age only. So there is no need to worry.

You can also use the growth chart to assess his growth yourself.
