Is this a worry? DD is 7 and has started flapping her hands when she’s excited. She often combines this with running and jumping, sometimes makes a bit of noise too although this has been going on for longer, at least the last two or three years. She also seems to do it when she comes out of school, as if to burn off the excess energy that she’s been holding on to at school. No other signs of ASD that I’m aware of and school haven’t mentioned anything. Should I be worried?
