Tilley -- boy, can I relate to the "I lost all this weight and now I look worse" feeling! It's still worth it to have all the fat gone, but it sure can be disheartening sometimes when we look in the mirror.
If the skin really is bothering you NOW, maybe go see a doctor and ask his/her opinion about the skin and babies and all. I think Mrs. Jim's right that they generally advise you to wait until after you're done having babies, but only a doctor can tell you for sure and then you can evalutate that info in terms of your personal life and future plans.
