My forth baby is 4.5 months old… noticed over the last 2 weeks she keeps looking at her hands, a lot. Now I have 3 other children, all with autism. I’ve never seen this ‘hand looking’ before in them. I wondered if this was a normal development thing or am I seeing signs already for autism 😭 she is very sociable otherwise! Has good eye contact, smiles, responds to people and everything else seems to be on target.. am I overthinking and worried or is this a normal behaviour?
