In need of advice!!

I just started a new job in july working at kroger, before i started that job i had taken a few years away from the workforce to focus on me and my husbands moving company. During that time we had our first child together. I was enjoying being a stay at home mom and was in no hurry to get another job but some things happened, our truck broke down and money got really tight around here. long story short i got the job and even though ive been missing the time with my children and husband things were going well. last Week i had to call out of work twice because both of my children were really sick. and this week there was a serious incident involving my daughter on the school bus so i had to take a day to handle that. now next week's schedule has been posted and went from 39 hours this week to hours 13 for next week. that's the lowest amount of hours i have ever worked in a week. My car broke down so now with me having to catch uber back and forth, working about three 4 hour shifts might not even make back the money i will spend in transportation. My husband and i are opening up a store and he thinks i should quit my job now and help him get things in order for the store. what do you all think i should do?
