I feel your pain. I won't take my baby to the gym daycare either and she's 10 months old. I don't feel comfortable having some teenager whom I don't know watch my baby so I can do something for myself. So, here's what I do...
- Wait til my husband gets home from work so he can watch her and I run to the gym for an hour (gives my mind a break and gives me the time I need to work on myself without having to worry about my little one.)
- I have a gym at home. I have a treadmill and some free weights at home so a few days a week, while she's napping, I'll go upstairs and lift. There's also a LOT of kalesthenic work you can do. Try these workouts: http://www.shape.com/workouts/routines/
- we also take lots of walks during the day. Walking for an hour at a rigorous pace will help you a lot, it'll get both of you out in the fresh air and it'll be a nice way to get out of the house.
- if nothing else, while your baby is playing on the floor or in the playpen, do some pushups, situps, squats, whatever. Your baby is at the perfect age to "help" you with your workout. You can do squats and lunges while holding him and there's a whole host of ab workouts you can do with your baby.

Kudos to you for making exercise a priority. Good luck!
