Hi - this is my first Mumsnet post...Had my little one by C section 13 days ago - she's great. Want to breast feed and have perservered through marathon feeding sessions, sore nipples and little support from my midwives ! Is it normal for feeds to vary in length - sometimes she feeds for 15 mins sometimes for an hour and a half. Should I be trying to get her into a routine for feeding and particularly bed time as at the moment I am feeding on demand and just getting through!
