Of course you can lose the belly. Make sure that you don't just do things like crunches though, because those actually don't work all that well. Look up a pilates move called "The Hundred". It's approximately 300x better at working the abs than crunches. Also be sure to work your back and core, because they work with the abdominals and can really tone things up.
I lost all the baby wt plus some....The belly is a whole other story. Jiggles more than it ever did b-4 I had the c-section. Yes i could loss it too....IF I exercise,which I don't, BUT should. Heck, I'm 42 chasing after a 2yr old, isn't that exercise enough...lol
