16 month old hitting

[daycaremom9]

I have a boy that is 2 1/2 that is having this issue also. He was biting about a year ago and his parents and I managed to get him to stop this. In the last 6 months he has been hitting. I've found that the time outs don't really work. I've been recently shadowing him and this seems to work better. If I'm unable to shadow him because I'm doing something where I can't follow him, I either have him follow me (say to the bathroom and have him wait just outside the door)or if I'm doing something in the kitchen, I'll have him sit at the table. Time will tell if I can teach him to stop being aggressive.
