my nice is 16 months old. At the moment she can't sit by her own unaided, does not crawl or walk, does not talk, does not point to things, and her eye contact is poor. My SIL thinks she is just too big and chubby to be bothered to move around and that it is a matter of time until she catch up. Apart from the fact that she is clearly developementally delayed in all aspects, my gut feeling is that there is something wrong with my nice and that she should be seen by a specialist or relevant person asap.
the thing is that i'm not close enough to my SIL to talk to her about this delicate subject and dont want to either hurt her feelings or maybe be wrong about it and regret having said anything about it!
Help Mumsnetters! what shall i do?
