What is the average height & weight for a 5 yr old?

Wow!Almost anything! Huge range of normal sizes for 5-yr old boys...Go to cdc website @ www.Cdc.Gov; type 'growth charts'; in the search box at the right upper corner of this webpage; click thru the menus until see boys charts geared for age5. Plot your son. He is probably normal. Average is the 50th percentile, but normal ranges from 5-95 percentile.
