I'm a bit worried about my ds, but I do tend towards anxiety and overanalysis. Ds is 20 months old from all his milestones he appears to be developing normally, sat unaided 6 months, crawled 9 months, walked 14 months, fine motor skills seem good, has around 20 words, v sociable and loving child. He is v sociable with other children, he has good imaginative play. Ok these are the things I'm concerned with he is a v v picky eater maybe only 4 foods he eats consistently, he moves around a lot, finds it hard to sit down for a whole book. He tantrums which I suppose isn't unusual but during a tantrum has sometimes bitten himself or his sleeve and hit himself, I guess he's expressing anger. Also he handflaps when excited, something I hadn't seen before. Are these red flags for autism
Or is it just his age? Thanks
