Help!

I don't know how to fit in my workouts! I have a 10-month old and I teach 7th grade, so you can imagine how exhausted I am most of the time. LOL I've been on Fall Break for 2 weeks, so I've had plenty of time to exercise. I go back to work next week, though, and I'm already getting nervous.

Here's my schedule:

5:30am - breakfast, shower, get ready for work
6:40 - leave my house for work
4:15 - pick up daughter from baby-sitter (sometimes I have meetings and it's closer to 5 before I can pick her up)
5:00 - fix supper, eat, clean up kitchen
7:00 - Bath & bedtime for baby
8:00 - crash on couch with hubby & watch a little TV, read, etc.
9:30 - start getting ready for bed

Help! I'm not sure what to do ... get up at 4:30am (yikes!), or work out really close to bedtime. I don't really like the idea of working out at 8pm - I'm usually exhausted by then and I need some down time to maintain my sanity. I'm really trying to get in shape and would like to be able to work out at least 45-60 min. per day; I'm just not sure where to squeeze it in. Any ideas?
