How did people go with losing weight?

After my 1st the weight fell off. It took ages to lose the weight after my 2nd, I was still 8kg heavier 12 months after the birth, which I put down to going back to work and not having time to exercise as I was sooo tired. I lost that weight in 3 months as we were getting married and had to fit into the dress I had brought.
After my 3rd I retained about 4 or 5kgs, but got preg when she was 9 months old so I wasn't worried about it.

I got on the scales today and was amazed as I am only 2.5-3.5kgs over my ideal weight and Jessica is 3 months old.

i guess weight loss after preg is a big concern to me as my Mum just couldn't lose weight after she had her 3rd and is now very overweight and will never be back to where she was, and she was smaller than I have ever been. I don't obsess about it, but I am conscious of it as I want to healthy.
