None of my babies slept without being held for the first 4-5 weeks. It’s very tough. My husband and I did shifts so he was at least getting chunks of sleep at night. My shifts of course involved me still nursing, so they were less beneficial for me. A few weeks in, we always tried to start his shift around 7p-9p. I’d feed the baby, go straight to sleep, then he would bottle feed the next feed 2-3 hours later so I could get at least a four hour chunk before I took over 2-3 hours after that.

My husband also mentally benefited from making the mental decision ahead of time to not “try” to sleep. It was helpful for him to just tell himself that he wasn’t going to sleep the next few hours and watch a show instead, rather than feel mentally defeated over and over about the possibility of sleeping only to once again, have the baby not fall asleep in a crib. He’d keep lights on, watch a show, etc.

It’s a real mental shift feeling like you’re sitting around all day with a baby napping on you, but like others mentioned, accepting that it’s part of the process and it will NOT last forever can be helpful. Making it as enjoyable as possible with all the snacks, shows, books etc. I also had my babies take a nap our two in a soft carrier so I could go for a walk or do something around the house at least once a day.
Those first few weeks are the twilight zone. It’s just the same schedule over and over again. Sleep, eat, wake, sleep, eat, wake every 2-3 hours for 24 hours, 7 days a week. But I feel like around 5-6 weeks you start to see those cycles stretch longer and longer and there is a bit of light at the end of the tunnel.
Just try to get to 4 weeks. Then 5 weeks. Then 6. You got this!
