I have a full time 2 year old i watch and he has been with me for almost a month now. This past week he has started hitting all the kids, even if they arent playing together. He will just walk up to any random kid and hit them really hard (most of the time with a toy). I have tried talking to him, being stern, putting him in time outs but nothing seems to work. Any advice would be so much appreciated as I am at a loss.
