My DS is 17 months old and at the moment he's only saying mum - no other words at all. I talk to him all the time and try and get him to copy me but he dosen't. He also hasn't clapped, waved or pointed yet. The only thing he does is put both hand soap in the air when we say "yaaay". Has anyone else had an experience like this with their little one's that can re-assure me? I'm going to phone the health visitor in the morning- it's just upsetting me so much when I see other toddlers saying lots of words and phrases. Feel like a failure of a mum.
