Yes, get a regular babysitter. My mom takes DD one evening a week so I can get my serious workout in. And, early Sunday morning while DH and DD are still asleep, I get my second good workout in for the week. Pretty much every other workout I include DD--push in the baby jogger, pull in the burley. She even likes to get her bouncy ball out and mimic the ball exercises I do for strength training.
The other option I'll be looking into this winter or next year is a YMCA membership. DD will be old enough to do Tumble Tots or take a swim class on her own and I would be able to attend a spin class during that time. They also have a day care set up for members.
Good luck! It's so hard to find balance, but if you are committed, I'm sure you'll find a way!
