DD is 5 in Feb. She literally cannot sit still. When having screen time for example she moved her legs, touches things, swings off the door handle, lies on the floor. It is the most irritating thing! She is a nail biter and often biting her nails. When in a shop she will touch everything and just will not listen to being told no. However at pre school apparently this isn’t a cause for concern. They haven’t noticed anything untoward. She can sit nicely when playing something she really wants to play with. Should I be concerned?
