We are not very concerned about his size as his dad, my hubby is a very healthy 5'6, with a 30 inch waist and 26 and a half inseam..: ))
This does my son good in dealing with his size!!
When he was in 3rd grade I started to let him walk home alone from the bus stop on our corner. Little did I know that all the moms on the block thought I was some wacko letting my kindergarden child walk home alone...LOL...I finally found this out last September when my daughter started at this school for Kindergarden with the same bus stop.
In 4th grade he made friends with another 4th grader so they started playing at the boys house after school. The mom asked her son why she was hanging out with a younger kid, turns out my son was older than him by 4 months.
I have so many stories like that I should keep them in a journal for when he gets older!!
