I'm trying desperately hard not to worry (and not google), but I am a little concerned about DS' speech development. He has never really said any clear consonants such as mamama, dadada and I'm starting to wonder if he ever will. He kind of babbles things like ga-ya-ah and makes - mainly incoherent - chains of noises to himself (especially when eating or in his cot in the morning). He'll also look at us and say "aaah" in a tone of a question IYSWIM, so he is vocal but not in the traditional sense.
I'm sure his hearing is fine as he will turn and look when we call his name and if I ask where daddy is, for example, he will look for him. If I say "give to mummy please", he'll hand me what he is holding so I'm sure he can hear me.
He's just turned 12 months and is a lovely happy giggly boy (with the odd tantrum as to be expected)and does, on the whole, make a lot of noise (squealing, laughing), just no words or anything leading up to one. I'm just wondering if this is unusual and when I really should start to worry.
Many thanks
