E.T.
From everything I have heard, getting your shape back is harder the second time as you have been stretched twice, rather than once. Personally, I am pregnant with my second, but after the first, I dropped 7lbs below my prepregnancy weight to look similar to what I had before.
Additionally, work on the crunches, the lower abdomen is muscles and they need to be retoned.
Good luck. I am due on Christmas and will worry about my body shape come 6 months after that.
