I actually put it on while bf (I don't think it as due to bf as I bf until DS was 33 mnths old) but I have lost 10+ kg and realised recently that I lost most of it after I weaned. When I was bf, especially when DS was feeding regularly, I was always hungry and I just don't seem as hungry as I was.

I remember reading that it takes 9 mnths to have a bub and that we should be gentle on ourselves and give ourselves at least 9 mnths before we even begin to worry about that. I think adjusting to life with a newborn plus other kids (or not as was my case) is enough in those early mnths
