Part-time jobs that fit around childcare - 18 weeks in

I am looking for part-time work that fits around school hours and found a few evening shifts near Boise. I have been trying to stay organised about it. Shifts are four to six hours and the pay is weekly. Has anyone worked these shifts?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
