My son, currently 11, has had many health issues. He had chronic ear infections, RSV
, asthma, pneumonia (an uncountable number of times). He heard muffled for 2 years, until the tubes went in. He never crawled nor walked until age 2 (after tubes). Sorry for the back story. We are know into elementary school, and he was always immature. I was told initially it was due to all the illnesses and hospitalizations. Well we are currently in 4th grade.
