I haven't gone back to work yet (still on maternity leave) but when I do, I'm returning to nights in the NICU. I actually prefer to do this. By working nights, I'm not going to miss my baby growing up like I would if I worked day shift - then I'd have to put her in daycare since my husband works a regular M-F 9-5 job. I will have to find help once or twice a week so that I can take a long nap before and after work, but since at least one or two of my shifts will be on the weekends when my husband is home, I will not need very much childcare at all. I only work 3 12's a week, so I have more evenings/nights off a week than on. My husband is used to me working nights, and the days I work will be his special bonding time with the baby. My mom worked three evenings a week when I was a kid and I remember those being the days that my dad fed me dinner and tucked me into bed. It was no big deal and is actually one of the reasons my dad and I are still so close!
If you work 5 8's a week, I can see why your husband might get a little upset if you've never worked nights before and he's not used to having the bed to himself. But then again, you're there all evening long in that case and get to spend time with your family...
Most of the nurses I work with work or DID work nights when their kids were small. It just makes things easier for childcare.
But you have to do what feels right for YOU and your family.
I wish you luck in whatever you choose to do!
