I am in my first semester of the ELMSN-FNP (OAK) and I also have 2 little ones. I really do not think it would be possible to work. Because it is 17 units, something already needs to get sacrificed, and sadly for me, that has been time with my children in addition to not being able to complete all of the reading. ... I am not even sure when I would work if I decided to.
However, I do think anything is possible if you believe it is, have the resources you need, and the support to get you through it. As of now our schedule is as follows, 12 hours of class, 6 hours of lab, 8 hours of clinicals, so that is 26 hours total. In addition to that, it is expected that we will put in 2 times - 3 times the hours study time outside of the classroom. ... I am lucky if I can get in 10-15, but am also finding that that is enough for me.
Most people are offered plenty of loans, especially if you have dependents. We are eligible to sit for the NCLEX in 15 months from our start date.
Best of luck to you!
