Is that too much?

Is working 7 days a week a lot? My S.O got offered a job potentially, and he would be working 7 days a week, 8 hours a day. But his day would start earlier around 5am and he would be out around 3pm. Any new moms, do you think that’s too much? He currently works 12 hour days but only 4 days a week. My baby is due in March ! I just wanna know how any of you with kids already would feel if the dad was gone every day? Money wise I feel like it’s a good opportunity but we also don’t know what it’s like to have a baby yet
