My baby seems love to cry at midnight when I am deeply asleep. I have to get up and check his diaper, not wet. But after I feed him, he doesn't cry any more and back to his happy dream. Is he really hungry at midnight? Why midnight?
Babies are suckers for routine. And most babies wake up during the night sometime to nurse or take a bottle. You're lucky that he's regular like that. My son has always been random.
