To be honest I probably wouldn't have used the word discipline except that it's in the title of this forum. Sorry for any confusion there. I have no desire to punish my infant or anything of that sort.
I have been using "ow" and "soft touches" or "gentle" ... I wonder if I'm not being consistent enough. And she does get plenty of tactile stimulation (at least from what I can tell, she just gets really excited and has to slap mommy's chest sometimes)
I like the idea of putting her down and walking away, but doesn't that send a message of negative reinforcement? I'm not sure if I should be practicing positive reinforcement or negative?
I really appreciate the replies to this. I know it's a game to her and I understand that ... but sometimes man, she hits hard!
