Taking a short leave from work?

Anybody taking a short maternity leave? My husband has extreme stress and anxiety at his work and is wanting to quit his job (teacher at an inner city school). Instead of me taking an extended unpaid leave, I could go back to work ASAP and he could stay home with the baby. I'm a teacher too and I have 10 days of paid time off I can use (2 weeks). I might could have 3 weeks off altogether because spring break is the last week of March. I'd only have to work for a couple of months, then I would have the summer off.

Edited to add: I'm covered under fmla, but the time off is unpaid.
