Part time job while in school?

Does anyone here work very limited hours while going to school? I just finished up my cna course last week, and took and passed the state exam today. I took the course because it was a pre-req for the nursing program, which I will be applying to in a few weeks. But ideally, I'd like to work as a NA while I'm in school. I won't be able to work enough hours to really make any money, but I'd like to do what I can for the experience. I also have young children and dh works on the road during the week, so that even further limits the hours I can work. I did see a few job postings at the home I did my clinicals at that were for only 16 hours per pay period (days) and every other weekend, but I have no clue how that works- is it usually rotating days or do you think it would be possible to get set days for part time? My fall schedule leaves me with Tues and Thurs completely free. Would they look at me like I was nuts if I started applying for jobs saying I can only work those days plus weekends? I can't do every weekend, dh would have a fit, but I can work any shift on the weekends, but only days during the week. I'm just so confused at how to go about filling out applications with my goofy schedule. I've been self-employed for the past 6 years and a SAHM for two years prior to that, so I'm very nervous about interviews on top of it all!

I was really sad to leave on my last day of clinicals last week, and would really like to find something where I can get a day or two while in school!!
