Any mamas that have gone back to work have same or similar schedules as your partner? If so, how are you managing sleep?

My husband wakes at 4:45a and is home by 5p, I will be (I go back in 3wks) leaving the house at 7a and home by 5:30p. My departure time includes dropping our baby boy at daycare and hubby will be picking him up. Our little guy is not yet sleeping through the night and I'm not expecting anything to change in the next 3wks....I mean it would be great if it does, but I'm not holding out hope. We've been pretty consistent with his bedtime routine, but he keeps waking up at 1:30 & 4:30 for feedings. We are all usually in bed by 10p at the latest.

Right now, I put up a little bit of an argument about not getting a lot of sleep, but hubby keeps insisting "you can sleep when he sleeps during the day". Technically, yes, but sometimes I use that time to do some laundry and either way, that possibility ends in 3wks.

So we just had a huge argument where he threatened to quit his job so I could sleep. 😒😑 I said some smart-ass-y things too.... we're both at fault but we're both just tired and hitting a wall at finding a solution.

I'm willing to take the late feeds for now, but I'm looking for advice on how we survive this schedule AND manage to keep our marriage together when I start back to work.

What has worked for y'all?
