I hear ya..I still look like I'm about 6 months pregnant too slowly working on it, but I really should have started way before now!
i can't remember what it was, but there are certain foods you can eat that help to burn the fat around your waist/tummy area (might have been dark chocolate?) of course in moderation though..lol.

Do exercises that work your abs, such as sit ups/push ups, pilates movements are great too. A good tip I was given is to walk everywhere (even around your house) with your tummy muscles tightened. The more muscles you can work the more calories you will burn. Cardio workouts are good for burning calories too, maybe see if your local library has any exercise dvd's you can borrow?
Walking pushing a pram (especially if it's uphill) is a good workout too, even more so if you remember those tummy muscles!
