I was well supported in hospital by midwives but was lucky to have most things go 'right' for me. I had colostrum from 9 weeks into pregnancy and bubs came out (c/s at 39 weeks) looking for boob. It was still somewhat invasive and intimidating though -- I was wheeled into recovery and had midwives pulling down my gown and grabbing my boob before they had even introduced themselves. One actually realised this and said "oh, sorry I'm so-and-so, I'm a midwife". DH was like "so you do work here then and haven't just come in off the street to grab at my wife's breasts".
Over the next few days I got some conflicting info about how to latch and hold bubba, but on the whole the midwives were supportive and encouraging, checking in regularly on how I was going. Only one MW really upset me - another had told me to buzz her when I fed so she could check my latch. So I buzzed and another came in, looking stern and annoyed and made me sit in a chair even though I wanted to feed in bed and basically told me I was doing everything wrong. I got teary and stressed. After I got home I drove myself nuts trying to latch bub in a particular way when he didn't seem to want to latch like that. He was gaining weight and I wasn't uncomfortable so I just let him latch how he wanted. He's 14 weeks now and in the 90th percentile for weight so it obviously hasn't harmed him.
I do realise how lucky I have been though -- baby who wanted to feed, milk came in on day 3, no tongue tie etc -- and it was still quite stressful at times. I felt like I was being given a 'good girl' label by midwives and child health nurses for these things that were really just luck. My sister is due in a month or so and her hospital has told her she won't be staying for much more than 24 hours. I think it would be very difficult to successfully establish bfing with so little access to immediate help. I already plan to pass on all the info I found helpful.
