I lost all my babyweight bfing relatively quickly. Definitely by 3 months I was back to "normal" weight for me (58kg) but kept losing weight so that by about 5 months I was about 4-5kg lighter than I usually am). I continued BFing for 14 months and my weight remained constantly at about 53kg, but now I've stopped BF I've put on quite a bit of weight... He he. Guess I needed to eat less once I stopped being in the milk production business.
