Do I wake up or sleep in?

Ladies, I’m feeling a bit like a slacker lately. I started a supermarket nightfill job 3 months ago. I work 9.30pm - 1am and get home around 1.20am. It’s a very active job, but easy enough. I get home, do my usual bedtime routine and I’m usually in bed and asleep by 2am. The morning after I work my husband takes the kids to school for me and I sleep in till around 10am.

I’m starting to think that maybe I’m being to lazy by wanting my 8 hours sleep. Most of the other mothers I work with get up at 7ish and they take their kids to school (kids are both over 9yo) I’ve also had someone mention to me that they’d get up at normal time if it were them. What do you think? Should I just women up and be OK with 6 hours sleep? I’ve had to do it a few times because my husband has had early meetings and I’m buggered by dinner time. My husband said he doesn’t mind doing it, but he made a joke about feeling like a single father on those mornings. I gently reminded him that’s how I feel when he goes away on business for a week at a time every 6 weeks or so.
