Mummies, please share your secrets to weight loss after birth...

One of my friends lost her weight mainly through breastfeeding.

Also, she took the stairs everyday when she brought her baby down to the park (her main form of exercise). Haha.. and she said her baby was her weight training (still is) and she thought those helped in her weight loss.
