My little boy has just turned 1 and for a while now he's been pinching, scratching and pulling hair. I know most babies do these things occasionaly but I feel like maybe he does it too much and its starting to annoy people now and they don't want to sit with him because the come away with scratches all over their faces. He laughs when he does it and laughs even more when we tell him no. I guess I just want to know if this is normal? Is it a phase?
