For me, definitely lack of support. i had all sorts of problems with DS#1 and stayed in hospital for a week and although the midwives tried to help i didn't find them very supportive at all. One even said to me 'welcome to the real world' when i was crying when feeding due to horrendous c/s scar pain. The hospital i was at had a lactation specialist (i found out afterwards) but no one asked her to come and see me. I gave up after 2 weeks. I was lucky with DS#2 that i didn't have any probs and he was a great feeder so still b/f him now.
