Usually the moms will be the first to notice something is different. My advice, stop guessing and get a professional advice. Don't simply listen to Tom, Dick & Harry and waste your time.
When I told my friends that I wanted to get my son checked out last time, they asked me not to go and get him labelled "so what if he is labelled? Are you going to spend the time and money and go for all the therapies?". I am glad I went ahead with my own instinct and got help for my son. Now I looked back for the past one year, I wanna laugh at myself for crying like a mad woman for weeks and nearly went bonkers.
