Hey all! So today my 7 month old had his check up and his height is below the 1st percentile he only had a nurse do his check up and she didnt mention anything. His bmi is good but the percentile thing got to me a little. How big is everyone elses 7 month olds? He is 2 feet. And a little over 16 pounds. My other child is small weight wise. My four year old is only 32 pounds and has always been skinny but not really short.
