I don't know how else to put it. DS has always been different compared to other children. He is very loud and his brain seems to go at 100 miles an hour. Just the other day he was talking to me and stopped half way through and sighed then said 'I just have so many ideas'. He will often talk complete gibberish about dinosaurs or minecraft to people who clearly have no idea what he's talking about and often doesn't stop for breath. He also thinks that everyone wants to be his friend and will not take no for answer. A child can be showing very clear signs they don't want to play/talk and he won't stop pestering them. He's gotten better at this but only because I intervene or try to explain not everyone wants to play and talk all the time. He just doesn't seem to pick up on social cues.
Just before lockdown his teacher told me that someone came in to observe the children and DS was one of the children they picked up on. I asked what for and she said being quite flappy (not too sure what she meant by this, he does struggle to sit still sometimes or do silly things but IMO normal for his age?) and covering his ears a lot. He never did this either at home until very recently and it's not all the time (usually just when his baby brother cries). She also suggested I get his hearing tested as he's very loud and asked if I was happy for a referral to be made. I said yes but obviously it's all on hold now and I don't know what to make of it all. DP thinks he's fine and nursery never had any concerns but as I said I've always noticed he seems a bit different from other children. What should I do?
