My 7 week old just will not sleep in the day no matter what I do. I do everything you’re supposed to do: short wake window (no more than 1 hour), look out for tired signs, do literally anything I can do get him to sleep. I rock, shush, swaddle, push in buggy, feed, put in sling, sit in a dark room, offer a dummy (not interested) etc. But nothing works. I’d do anything to get him to sleep. If he wanted to sleep on me all day, no problem. But he doesn’t. He’ll fall asleep then 2 minutes later his eyes ping open and he’s awake and the whole cycle starts all over again. He eventually crashes out for the evening at some point between 7 & midnight. I’m tearing my hair out. Please help me!
