Congrats on #5....little envious here.....ive fallen pg twice whilst b/f.....1st time (pg with DD#3) i had awful m/s.....vomitting every morning right up until 11wks, very, very tired, and just generally feeling very rotten. i breastfed up till 12 weeks pregnant and then weaned DD#2...fell pregant again when DD#3 was 11 months. I wasnt as sick this time.....but she was really only feeding in morning and before bed. I weaned her at about 8 wks pregnant.
So to answer your question. Pg #3 was awful in terms of b/f as well....Pg #4 wasnt as bad, but i weaned earlier.....
