Oh, sweet momma, don't get discouraged about your weight yet! You just had a baby eight weeks ago. I know it's not fun, though. I have a hard time with it too. But given time and work, you can get it to go back to mostly normal (if not completely).
DIET IDEAS:
Eat protein (won't add fat), and limit your carb intake. That means to take it easy on breads, cereals, rice, potatoes, etc. If you can, toss any sugar and sweet. No sodas/juice, just water to drink. You want to focus your meals on protein. This'll keep your blood sugar even (even you if you don't have diabetes!) and will make you not gain weight and make it much easier to lose the weight. I've done this, and it works. You want to make sure you eat plenty of vegetables. Those are free foods. Yummy salads with yummy toppings are good free food (be mindful of what dressing you use). Also, eat fruit as it has plenty of good vitamins in it for you.
WORKOUT:
Get the book "Lose Your Mummy Tummy" by Tupler. This book is made specifically for mommas who've had babies. Prior to this book, I didn't realize situps and crunches actually make the poochy mummy tummy worse! The book focuses on pulling the muscles back in place and flattening them. Definitely get this book!
For some cardio, I'd suggest getting some Zumba Fitness DVD. It's fun cardio that gets you exercising well. Do however much you can...20 minutes, three times a week. Or 20 minutes a day. Just something like that.
These things will help you lose weight and/or pull your muscles back in place.
Remember it'll take time, though. Getting enough sleep is also very important (not necessarily easy with new baby, but try not to stay up too late if you're a night owl). And, make sure you eat breakfast. That is a very important meal so that your body doesn't start holding fat. Eat every three hours if you can, something small and healthy.
Anyway, hope that helps!
