I really need help getting my 4month old on a schedule. He will NOT sleep at night especially not longer than 1.5-2hrs. It's draining me. At first it was no problem but I think that was just the first month when I never slept or anything, but now it's all catching up. I have not letting him sleep during the day, bath time routine, quiet time, plenty of feedings during the day so he would stay full, and he still just won't sleep. If I do keep him awake all day he's super fussy screaming so I'm really at a lost what else to do.
