Debating if it's even worth?

I decided to get a part-time job at night when my kids worked. I told them I could work Tues, Fri, and sat nights from 5:30-9. My kids work till 9 but then they told me I need to work till 10. So now my husband has to get the baby and bring her out at bedtime just to pick them up. I decided to look at my schedule and I work today and tomorrow then I don't have back till the 14th! After realizing how their time goes in for the week, I would only be getting a paycheck for 4 hours!!! Is it even worth??
