Need advice please!

Babygirl will be 4 weeks on Sunday but it’s time for me to go back to work. I basically have to start over since my last job let me go because of maternity leave. I had a interview today and got the job but it will be midnights 11p-7a. I’ve never ever had a midnight job, I’ve always worked dayturn. Mind you I have a 7 year old that I’ll have to take to school by 8am and still handle my newborn during the day until her dad gets home. Any advice on how to get sleep and how to get into a routine of a midnight schedule????
