Baby Fat

Ok so this is day 5 of my diet and I have already lost 9 pounds!!! I love watchiing the pounds fall off but, I have a question for all the moms out there. I had 3 babies in two and a half years (yes I know CRAZY), one in Jan of 2008, one in Jan of 2009 and my last was born in Nov of 2009. I have the horrible flabby belly hangover, how do I get rid of it??? Anyone have any suggestions of excercises to help me rid the loose skin???
