@perfectlove25 I breastfed (with supplementing for a little while) so it was a little different from if you’re formula feeding, but our routine was:
9-3 was my shift, 3-9 was my husband’s.
Whoever was on shift would sleep when they could and just get up with the baby when he woke up. If it was me, I’d breastfeed then top off with formula then change his diaper then rock/nurse him back to sleep and put him down and go back to sleep myself. If it was my husband, he’d bring him to me, I’d breastfeed then he’d take him away and change his diaper then top him off with formula/rock him to sleep so I could breastfeed but not have to leave the bed at least.
For the first 2-3 weeks, whoever was on shift would sleep on the couch with him in a bassinet in the living room because he didn’t love sleeping independently at night and that way the off shift parent could sleep without any disruptions. Once he got decent at sleeping in the bassinet, we brought him to our room and we all slept in the same room, but the same rules applied. Additionally, whoever was on shift would take him to the nursery for the diaper and rocking so that the other parent could stay in a dark room and get better sleep.
Eventually, my supply was good enough and LO slept well enough that I’d pump one bottle each morning for my husband to give overnight so I could sleep through an entire feeding, and that was wonderful.
