My ds is 7 mo and ebf. I never really anticipated getting to this point but now that I have I want to continue to 1 year (back to work at 11.5 months). I read on here the other day about someone wanting to bf past the mmr jab. Is there any particular reason for doing this? Just wondering if I should aim to keep going a bit further if so? When do they get mar- is it about 13 mo?
