Don't know where to exactly post this, so I'll try here:
a friend of mine has to go on a business trip for 3 days and is worried that she'll "lose" her milk... LO is 12 mo and still nurses a lot over night (reverse cycling I believe).
I told her that she shouldn't worry at all but then I had doubts... she never pumped, so bringing a pump is not an option... I told her that just to be sure she should empty the breasts a little at night with hand expression, so to tell the body that it shouldn't stop producing...
