Namechanged for this.
I just wondered if people could advise or reassure. I have a 4.5 year old DS who is exceptionally bright academically, very good concentration span, and was always very sociable and chatty too - would talk to anyone! Now I used to be worrying about my DS (as a toddler) because autism/aspergers does run in the family, and he did seem very focused and often had massive tantrums (biting/pinching etc) about having to go into the pushchair. I worried because I thought we were perhaps seeing bright when in fact he could just concentrate for a long time and had a good visual memory. I worried that maybe we were missing something because we were so close to the situation. But now he's just started school and his teacher (and previous nursery) are all very impressed by him and don't seem to have any such concerns, and I have realised that this is just who he is.
So when DD came along I just thought maybe she'll be the same, but possibly not. In fact, she is in many ways the opposite! Although she is clearly still a bright child (knows her colours and can point out things in a picture book, knows animals and their noises, likes singing songs, that sort of thing) she is nowhere near as sociable (will try to avoid people when they talk to her, clings to me, will take an hour or more to get used to a visitor being here). She also has a short attention span, although I am thinking it is a normal sort of attention span for a toddler, and maybe we were just used to DS being very focused on everything. She is very clingy at the moment (this developed during a recent illness and never went away) and I am starting to feel worried due to other people's reactions (relatives, including my DP) that her development is a concern. DP worries she is not as interactive as our DS. She doesn't always answer you when you ask her a question (i.e. "What animal is that DD?" wheres for DS it was almost like it was a game and he enjoyed answering questions. She spends an awful lot of time singing. She does point out cats and dogs etc in the street (well she says "Cat! Byeee cat! Byee cat!" for example.
I know it is difficult to judge from brief description but should I be worried? I am not sure whether people are just comparing her to DS but then on the other hand how comminicative should a 22-month old be?
