Great work, i really hope the rest of your breastfeeds are like this one.....I found the first 12 weeks of every one of my girls hard with breastfeeding....infact with #3 i got mastitis when she was 9 weeks old....I look the first 12 weeks as the 'getting to know you stage' and we're allowed to cry, scream, rant and generally just feel like giving up....but its now, when you get to 5,6,7 months, b/f gets really easy. I find i know what Sam wants, she knows how my boobies work,and we just fit like a puzzle.
Its worth persevering, it really is.
Hang in there...
