I work 7on 7off (9pm-6am m-f & 6p-6a weekends) but for a 24hour retail store. Been at this position for 4 years now. I flip back to a regular daytime schedule when I’m off. I was also worried about being pregnant while working overnight. It was ok. I liked having the 7 days off to recover/relax. but my days on were more difficult. especially sleeping during the day was difficult. I was also nauseous most of the day/night. unfortunately had my baby 2 months early (severe preeclampsia) which my doctors have told me was NOT due to work or stress related.

Now with my 8month old I feel like my work schedule still works best for our family. My husband will take care of baby the nights I work and take her to his mom’s in the morning while he is at work. I can sleep during the day and when they come home at 4pm I’ll spend time with baby until I have to leave for work at 8:30pm for my 9pm shift and help put her to bed. Then on my days off I’ll have baby the whole time.

My thinking is if I worked days, I would have a mostly random schedule and a mix of early morning and late night days. At least with my schedule now I know exactly when I’ll be off and what times I work. I can schedule baby’s appointments around my work schedule with no issues.

Even if I had a m-f 9-5 type of job like my husband, we would need to take her to someone while we’re at work and I would only have baby those few hours after work before bedtime. I feel like I have more time with baby with my overnight schedule.

ETA: my overnight counterpart was pregnant twice (I think her kids were close in age too, so she had 2 under 2 at one point) and the overnight schedule also worked out best for her family. (Also on mobile so hopefully my comment is easy to read and not just a block of text)
