K.P.
A., did the pediatrician mention that the ear infection itself could be causing your son balance trouble? My son's ear infections were so continual as a tiny one that he didn't even fuss over them. The only way we knew there was a problem was in the doctor's office when the doctor looked at his ears. Because of the infections, though, my son had several mild delays and had to be evaluated for early intervention. That process couldn't be more painless.
The good news to this for your son is that studies have shown the longer and more a child crawls, the better his reading skills. Crawling has such a major effect on reading, in fact, that when sixth graders with low reading scores are made to crawl around just once a week, their reading scores improve drastically. My grandmother, a teacher, saw this first hand with her own students. So even if your son doesn't want to walk on his own much, he is sure to want to read. I hope you have your library card ready. *S*
Infinite Blessings!
