So suddenly in the last few weeks the baby went from two feeds a night (where baby was fed and went back in the cot) to sleeping 3 hours solidly then nut going back to sleep unless he's attached to my boob, and if he comes off, screams and screams and won't settle. I'm tired and have been sleeping with baby in bed on my boob just to get some sleep. If this sleep regression? Or something else? Do you think maybe he's not getting enough milk during the day and that's why? I'm tired and need suggestions 😂 and he won't take a bottle anymore at all either so i can't use that to make sure he's getting enough 😢
