My 5.5 month old gets up 3-4 times throughout the night. I have the suspicion that he can't put himself back to sleep when he wakes up, and is using me as a paci to do so. BUT, sometimes I think that he really is hungry because he will eat each time. I just don't know! He used to take a binky when he was a newborn, but not anymore. Would it be too difficult to reintroduce it again to see if he'll take it? I need to do something because I wake up every morning feeling like a walking zombie. I think I only got four hours of sleep last night! I tried sleep training him last month, but he is as stubborn as his father and he just cried, cried, cried. And when he cries, he CRIES. We call it his "mad cry." And, his cries escalate the madder he gets. (sigh).
