Unfortunately that is the way things go- but even moms who do not have c-sections tend to have a little flap of loose skin. It usually takes time but it will gradually start to look better. Keep your body well-hydrated with lots of water and your skin soft with plenty of moisturizing is probably the best thing you can do. Mine started to look better after a year and probably would have continued to look better had I not had more children:)
If you have future children don't despair, you can try for a VBAC. I am a nurse-midwife and I have delivered plenty of babies in the 10 pound range, it can be done and avoid further problems with scars and skin.
