I have twin girls, both 4 year olds and both very happy in school - keen to go, excited and happy when coming out. However, one of my twins doesn't play with anyone else, she plays alone and says she just prefers this. Teacher has verified this. She is bright, extremely articulate and happy. She can take or leave other children mostly and likes to be independent and do her own thing. She finds it harder to read social situations and sometimes seems to not pick up some cues but nothing dramatic. We have had some playdates and she has really enjoyed playing with the visiting child. She is confident and on track with everything. She has no problem with eye contact, no behavioural concerns, she can get more emotional about some things but well within normal 4 year old behaviour. She has an amazing imagination and is very cuddly and affectionate. I basically have I have no concerns but my partner has said she could be neuro diverse (Sorry, I don't know what the best language is to use, please correct me if this term is incorrect) because she doesn't play with other children at school and is confident and old for her years? I just don't see it. Would any of those things worry you? Sorry, I should add they were extremely premature but no adverse effects. Thanks in advance!
