I am not in the same boat, but I am a senior SRNA, and I know a few students who have been single parents and made it through. These students deserve so much credit, because they have worked so hard to make it through. Hats off to them for making it! Every time I get disgruntled, I think about what others do to make it through, and my sacrifices seem very, very small.
So, here's what they told me:
1. You have to have a solid financial plan, because work is not an option. Take this to heart, because it is true. I know a few students who do work in their senior year, but it is very sporadic, and they view it as "bonus bucks", not as a part of their financial plan.
2. You have to have a very reliable plan of childcare. Whether that's family, or someone you pay, you need to be able to count on someone to look after your kids while you are gone. And you will be gone - a lot.
3. You have to accept that you are not entitled to special treatment. You are coming into a program with kids, and you should be well-apprised of the demands of school by reading this board, so it's not a blind decision. Don't create tension in your class and at clinical by asking to be treated differently because you have commitments to your kids. You will really p^&s people off if you expect to get off at 3pm everyday because your babysitter has to leave by 4.
For what it's worth, one of the students told me that if she had to do it over again, she would have gone earlier, while her kid was younger, or waited until the kid was in the later teens, when she could drive. She went when her kid was a pre-teen, and it caused a lot of problems.
Also, another single parent told me that the best decision she made was to move several states away to go to a front-loaded program, and then move again to go to clinical. That's very smart. Alternatively, you could find a program that does everything in one location - classes and clinicals - with little or no rotation. It would be very, very difficult to be in my program as a single parent, when you rotate to different clinical sites every month or two, 10+hours of daily clinical time is typical, and a 2-3 hour daily commute is not uncommon.
Best of luck with whatever you decide.
