19mo dd hits me and dh if she doesn't get what she wants or if we're being affectionate with each other. We've tried all the obvious things, ask her to say sorry, say it's an unkind thing to do etc. but none of it is working. She'd say sorry then hit us again immediately afterwards, obviously still doesn't understand what sorry means!
Any advice on how to deal with this much appreciated, dh and I are tired of being woken up by an angry hitting toddler!
