I'm at my wits end. My 5 week old baby was a good sleeper at night initially. But for about 5 days now they're staying awake all night. I thought it may be the heat but it's cooled down now and it's still an issue. We have a solid bedtime routine - 9pm every night, changed and fed then into the bedside crib in a dark quiet room. Baby goes to sleep immediately. But like clockwork they wake up at 11.30pm and that's it until about 6am when they'll nap for a couple of hours. I do all the right stuff when they wake - nappy change, feed, cuddle and they fall asleep on me. But the minute I put them back in the crib they wake up and scream. Soothing them doesn't help, the only thing that makes them be quiet again is more boob. Then the cycle starts again. I just don't understand why they won't sleep in the crib again when they do it happily for a couple of hours after the initial bedtime routine.
Has anyone else experienced this and have any tips? Google only tells me how to set up the night time routine but not how to deal with a baby who refuses to resettle after waking. I feel like a zombie as I'm up all night and then can barely function all day. TIA to anyone who can help a desperate woman sleep!
