Re: So tired of the screaming/crying!
If its been happening with your pregnancy maybe it's really an insecurity about the changes coming with a new baby...I'm not sure how to figure that our, but maybe try some one on one time talking to him about it? And then just consistency I guess, and giving a lot of positive attention any time he behaves respectfully.
Can you get his daddy to step in some too? Sometimes DH has to "protect me" from my emotional response to DS. My mom told me once that God gave us husbands to protect us from our kids (not sure what that says about me & my brothers, lol)
