how to get rid off a muffin top

[Cricket]

The high waisted jeans will tuck in the mummy tummy, but they will make your bum look like it's two feet long, and flat. I'd say avoid them. (Check out "What Not to Wear" with Trinny and Susanna - saw them on Oprah. Wow.)
With the others, I'd recommend some excercise with tummy toning - aerobics with knee lifts and kicks, sit-ups and cross over sit-ups, etc. Also, avoid high-gluten bread. That's the really nice, soft, fluffy bread. Try whole grain, and especially rye instead. Much better for reducing tummy fat. Drink water like crazy. (well OK, not truly like crazy, but get your 8 cups in, if you can manage it. I lost 5 lb in 2 weeks that way, and then fell pregnant. )
Maybe buy some loose fitting tops that skim your body and hide the less flattering parts. They can be very nice and slimming, without looking saggy and baggy, or shapeless. Your pre-baby belly might be lost for good, but you can most likely improve it, and learn to dress in a new, flattering way. Head to the shops, and try some styles that you've never tried before! Maybe go at a quiet time of day, so that the sales ladies can give you good attention. Sometimes they have some great suggestions. And if there are some special pre-baby clothes that you really would love to wear again, maybe get one of those full body control top things. They are wonderful for smoothing everything out, especially for special occasions and formal wear.
Of course, by the time you've battled your way back to the closest you can be to your "pre-baby" self, you'll be pregnant again. It's happened to me twice now. But on the positive side, I've started each pregnancy weighing less than the one before.
All the best!
