i have a beautiful healthy DS who will be 11 months next week. He's been crawling and cruising for months, smiles at everyone, recognises his name, drinks from a cup - all the usual milestones covered...all except babbling or making any distinguishable sounds. All he does is blow raspberries and say "mmmmmm". My daughter was so different to this and I'm wondering if there is something wrong or if he is just too busy being physical to focus on talking. It's giving me sleepless nights as I feel responsible. When he was 4 months old ( and already pulling himself to standing) he stood up heldmy hands and then let go, falling back onto a plastic changing surface. I keep thinking this may have caused something, even though he has obviously progressed greatly since then.. Am I being over paranoid?
