I know this is going to sound totally insane, but I am determined to be a stay-at-home mom. In order to do this my husband would have to work the standard 3 12 hr shifts and then pick up 2 PRN 12 hr shifts, as well. Therefore, he would be working 5 12 hr shifts in a week (preferably in a row, nights). This seems like a lot to me, but he swears it will be no problem, as he has never had problems in the past with sleep or feeling tired. I'd love to hear any thoughts on this. Has anyone ever tried anything even remotely similar?
