Schedule

Hey girl, not to be a downer but your baby isn't likely to stick to a schedule this early on. Its going to take a couple months for things to normalize before getting into a schedule. Try having a sleep routine before instead, like warm bath, story, feeding and dark room. And make sure she sees sunlight during the day. At this young she has no idea between day and night and that isn't going to change for a bit. Hubby is going to need to get on board with the rough nights. But it does get better I promise! You got this!

Also if you need to track sleep the huckleberry app is super helpful!

I pulled up Pinterest they have some amazing ones to try until you find the right one

I’m assuming you’re talking about a schedule for yourselves? I.e. you are “on shift” from 9pm-midnight for example?
It’s hard to agree a routine in the beginning when you’re still finding your feet, but after a few weeks we did: 9pm i’d feed and go to sleep and my husband looked after her until her next feed (around 11ish usually) then I’d go back to sleep and he would settle her and be “on cover” until her next feed at 1am. I’d then cover from when she woke up until around 5am. Then he’d wake up with her and I’d get a bit more sleep.
In terms of babies schedule, I wouldn’t even think about it until around 6 months. You can’t put a newborn on a schedule and even then once you do, it’ll probably change monthly. Every time we’ve got a routine down, her naps change a week later🤣 and I imagine this will continue to be the case until she’s 12 months+

My LO is 4 months and sometimes her naps are 2 hrs and other times they’re 43 minutes

My daughter is currently 11 weeks old and we only recently hit the point at which she is mostly sleeping through the night. She feeds on demand 24/7, but after taking her outside to the grocery store and on walks during the day, she's now sleeping for a good 6 hour stretch at night, feeding once, and then going back to sleep for another 4-6 hours before her first wake window in the morning. She doesn't exactly have a set bedtime yet because she's still a bit too young for that. Still, I cannot express the relief I felt the first time she gave us that long stretch of uninterrupted sleep. I cried happy tears.
Don't worry mama, it will eventually fall into place. Especially once your LO is able to eat more at a time...I've found mine sleeps longer if her belly needs a good while to process that last feeding.

My husband would take his turn from 8pm to 2/3 am when he usually goes to sleep and then I would take over from then. Honestly getting those couple hours unbothered was everything
