Quick question for Mum's of twins (mine are just waking from their nap and don't like being left too long . Would love to know when yours started to talk - where they later talkers than your singletons? DTs are 21 months and are really saying very, very little - out, hat, there, that, yes and not much more. No Mummy, Daddy although one has maybe started to say Dada in the last couple of days. Is this normal? I seem to remember DS's had quite a good collection of words at this age. They do babble constantly and do converse with one another so it's not as if they're silent! Am i worrying unnecessarily? Better run but shall check back in a while. TIA
