Not many! Mine can say Mum, dada and no (doesnt say no clearly though).

The toddlers in my mothers group (all born within 6 weeks of each other) are all saying a lot more words than mine.

Our GP at 12 months (when he had no words) was recommending speech therapy. At our 18 month check up the GP was not concerned at all. I have had my DS added to the local community health speech therapy clinics waiting list anyway, although my family and friends think I'm crazy for doing so.
