I had a great Dr who once told me it takes a minimum of 12 months for your body to return to normal - longer after subsequent babies. My little sister who is a size 6-8 was horrified to discover although she weighs less than pre-pregnancy weight, her rib cage had increased in size. It takes time to rearrange your body back into position.
Keep up the exercise but try to have realistic goals when it comes to your body image. You have been under a lot of stress and this takes its toll also.
All the best!
PS - I looooovvveee my wii!! It can definately give a decent workout. Especially as it can be done whilst bub is asleep.
