DD is 21 months. She was born at 27 weeks and so is 18mo corrected age. She is tiny for her age (just gone into 9-12 month clothes) and isn't walking due to over-flexible hips and ankles, so 'seems' to be a lot younger, IYSWIM. Unfortunately the only other girl in her peer group is very much more advanced than her - was walking at 10mo, is speaking in sentences, etc.
DD loves to 'count' things/pictures by pointing at them one by one while I say the number words, but makes no attempt to say the words herself (she has an ok vocabulary - has a lot of animal sounds/words, various other words and a range of Makaton signs too). Being my first, I have no idea what is 'normal' development.
How soon might I expect her to say the number words? What about recognising letters/numbers? I don't want to be precious about it and push her into doing things which she's not ready. However, she's a bright little button (has taught herself some Makaton signs from watching Mr Tumble, knows how to unlock my phone(!) etc) and I don't want to hold her back.
How might I go about teaching her?
Thanks - Sorry if I sound a bit PFB - I know she's not a genius, but I haven't any idea about this sort of thing!
