How do you split responsibility?

We are not even two weeks in and my husband is having a full breakdown. This spins me into a cycle of tears because I don’t know how to do this on my own but feel like I need to do more to help him. We are both currently for work for the first 3 weeks.

Our current night time set up is that I change and feed the baby, and then I wake him to do the settling and transfer to crib, so I can sleep during this time. This amounts to us getting 4 ish hours a night. If baby stays awake, we both stay awake.

I’m tired but not totally broken by the 4 hours but my husband is actually having a full breakdown from lack of sleep. My problem is I’m not very good with the settling and transfer and more often than not end up waking baby up. Also if I’m doing everything, I’m only Getting maybe 2 hours of sleep in the night.

We have a toddler at home so my husband gets her off to daycare in the morning while I sleep and then comes home to rest until about 1pm. I also try and sleep during that time but i take the responsibility of baby during that whole time whether she sleeps or not.

All this to say obviously im not doing enough for my husband. How are you managing night sleep? By yourself? Does your partner help you with anything?

If by yourself how are you surviving with no sleep? I already feel like I’m dangerously nodding off while holding baby.

What does your split scheduling look like?

I will add we are not interested in bed sharing with baby

Edit to add I exclusively breastfeed
