For me I also had supply issues. My Bubs was 8 weeks prem so i expressed for 7 weeks as bubs had to be tube feed she also had alot of trouble attaching to me while in the hospital.I bf untill she was close to 5mths (3mths corrected), and at that stage she was bf every 1.5 -2hrs apart,including nights. For me complications at birth,affordability/availabilty of support and education were what i think were my main concerns.
