I cut back my schedule this semester - actually finished Nsg. 101 last semester and started Nsg 102 this semester, along with A&P2, but it was too much. Between a 2 1/2 hour drive 5x/week, long days at clinical, an impending divorce, and studying whenever I could manage, my kids were paying the price. Granted, the older ones (14 and 12) are self-sufficient, to a point, but I love being involved in all of their activities. The younger ones need someone there at home with them, and 2 days a week, when I was at clinical, I couldn't be, so my oldest had to babysit. It just wasn't fair to her, as she likes to snowboard each day when her homework is done.
So my new schedule is working better. Next year they will be a year older, and 3 will be self-sufficient while I'm gone (or just traveling home, so they'll only not see me for an hour), and I should have more study time with my science stuff out of the way. Hopefully by then I'll be in a new house, or he will be.
My kids are great though, and still offer to clean - sometimes! I tell them all the time what a huge help that is.
