Contrary to popular belief, the best time for a tummy tuck if you really want one is about six months AFTER you've delivered (either vaginally or via c-section). This allows enough time for your uterus to contract down to original size and for you to return as much as possible to your original weight. This is so that your muscles and skin get the tightest "fit" possible with a tummy tuck, instead of being "fit" over an enlarged uterus that is still around right after delivery...
