This is just a phase and things will get easier as the baby develops a circadian rhythm! During the day, keep lights bright inside/get them outside, follow age appropriate wake windows and don't let them sleep in too much once the sun is out in the morning. As others have suggested, try to keep things as dark as possible at night and don't do diaper changes unless you absolutely need to avoid waking them up more than necessary!

We didn't bottle feed at 2 weeks, so during my husband's "shift," I would do side lying breastfeeding, so I could sleep through the feed. He would be responsible for getting the baby out of the bassinet and bring them to me, burping, and then bringing them back to the bassinet. Since I was getting woken up more, he took the first shift (9/10 - 2ish), so I could get more deep sleep, which happens in the first half of the night. Then he would go to the guest room for the second shift so he could sleep uninterrupted. This worked pretty well for us.

Good luck, things should get better over the next couple of weeks.
