I remember it happening fairly early with DS1 and now with DS2 I think it may have arrived. He's seven weeks old.
When I saw my Ob for my checkup the other week he was insistent that you cannot get your period if you're bfing. I did, so wondering when others did too?
(I should add both my boys fed 1-3 hourly. DS2 rarely goes more than 2 hours between feeds)
