Working nights advice

A❤

Hi, I just interviewed for a part time night shift position. The hours would be 10:30pm-7am. Either 3 or 4 days a week, depending if I chose part or full time with benefits. I just worry about my life and sleep schedule should I get the job. I have a 1 year old son and my MIL would watch my son the days after my shifts to let me sleep. My questions are those who’ve worked these hours how long do you sleep afterwards? Should I aim to sleep atleast 6-7 hours or? And what about the day before my first night shift of the week. How would I prepare before my shift when I sleep “normally” the night before, take a long nap before? Any tips and advice would be greatly appreciated!
