At 17 months, really? Is that normal? Ds is 18 months and has very few words and while he will babble as though he is saying a whole sentence, what he's saying is not recognisable words.
He says daddy, mum, woof, meow, again and then there is "raah" like a dinosaur says and something which is trying to be "tickle tickle".
He has no problem understanding simple questions or phrases such as let's go upstairs or put that in the bin and can fetch items if asked to. He can't name anything and wont point to things in books if i ask him to but he knows that dogs woof and cats meow.
So is he behind or about right for his age? I knew there was a reason I stopped reading about these "milestones"
