My "go to" when I need to lose a few pounds has always been Weight Watchers. I lost 40 pounds on it years ago and have kept it off. Once in a while, when I see a few pounds creeping up on me, I get out my weight watchers stuff and start counting my points. Works for me every time! Also, you didn't way whether this is an option, but joining a gym with a free daycare (most have that option now) is a great way to get a work out in and the kids have a safe, supervised place to play while you work out. Good luck!!
