I'm 15 weeks preg with second and really keen to bf. I bf dd for 8-9 months.
It was really tough for the first week or so - she wouldn't latch on, my nipples were sore etc but we got there in the end. I'm so glad I managed to bf but get the impression it is harder with the second. Friends have given up much sooner and seem to think formula is far more practical if you have another small child/toddler running around (new baby due two days before dd's 3rd b'day).
any tips or personal experiences greatly received!
