What Is The Right Height And Weight Of A 18 Month Old Infant?

Posted on Thu, 19 Nov 2015

Question: I have an 18 month old son and I am concerned with his growth pattern. Since birth he has consistently been in the tenth percentile height with only getting up to 15 percentile at 6 months old. His weight has always been above 50 percent most recently at 65.

My husband is 5"11 and I am 5"3. I have an older daughter that is 3 years old and she is 95 percentile for both weight and height. I am concerned there is an underline medical condition we are missing. His pediatrician does not seem concerned but we do not have really short people on either side of our families. Thank you!

Brief Answer:
Any percentile between 5th to 95th is normal

Detailed Answer:
Hi....any percentile between 5th to 95th whether it be for height or weight is normal. I completely concur with your pediatrician regarding this.

An active kid is s well kid.

Any child who's between 5th to 85th percentiles of weight n's height and developing normally is a well child.
