I don't really do time outs for under 2's. I don't feel it's fair. They're young and don't know any better. Our job is to teach them the appropriate way to handle their anger and/or behaviour. We need to model behaviour for them. I use distraction or remove them from the area and use simple word instruction.

I try to remember that even children are allowed to be grouchy(aren't we all lol) but aggression is not so I focus more on that and less on "punishment" when they're that young
