I'm sobbing as I type this. I don't know what to do. My baby will not sleep. We have a bedtime routine that we've had since he was a couple of weeks old. He settles well and only very occasionally Wakes before midnight. But after that, i feel as if I'm in he'll. He woke at 12, 1:30, 2:30, 5:30 last night and wouldn't go back to sleep. I fed him at 2:30 and tried to just pack his back the other times. I'm losing my mind from lack of sleep. I don't know what to do. I've been doing blw for 2 weeks and I wonder if he's waking because he's hungry.. Or habit? Either way, I feel like jumping out of the window. What do I do?
