Looking into LIPO for trouble spot...Anyone else?

Second child left me with a flabby stomach and no matter what AB and CORE work I do, it doesn't shrink or burn. Has anyone tried (as a last resort) a Mommy Makeover or liposuction (Tummy Tuck)? If you have, what results are you left with? Recooping? Did it work to take this stubborn fat away? I'm not giving up on the workouts, but I feel like I have hit a concrete wall and I can't fix this any other way. I figure if my whole body is trim ad defined, why not have the whole package and get the stomach fixed too. :)
