I love my little boy to bits, he's a lovely cheeky, happy little man mostly. But he just does not listen most of the time. He won't walk nicely beside me, holding my hand. He wants run everywhere. He won't sit nicely in a trolley, he wants to walk but when you let him walk he bolts in the opposite direction. He fiddles incessantly, with everything, everywhere we go. When we go into shops he takes everything off the shelves. He won't watch tv for longer than a few minutes, he can't sit still, ever. He has zero attention span unless he's fiddling with something he shouldn't be. Toys interest him only briefly before he moves onto the next thing. I'm finding it so difficult to keep him entertained now it's winter. Is he normal, or do I need to worry? He's affectionate, loving, socially excellent and normal in most other respects.
