re: Terrible 2's: Toddlers Hitting & Throwing Tantrums

Ours is doing the same sort of thing, but instead of hitting, he's biting. It's the same thing with us, he doesn't do it at home and if he does we correct it immediately. The problem with us is he is an only kid, so he has no interaction with kids around his age except at daycare and we don't get to see that.
They all go through these stages and it's frustrating but all we can do is correct him when we see it and teach him right from wrong.
