I am the same as Cal, feel very pasionate about people getting the right support - which ever way they feed.
DS1, I really struggled, there was absolutely no support from HV/M/anyone, he was feeding every hour for half an hour (so half an hour on, half an hour off) 24 hours a day, I had so much milk my boobs really felt they were going to explode, it was sooooo painful. Everytime I fed him on one side the other side would leak at the same flow rate so every time I fed him it was a change of clothes for both of us because we were just drenched. I had an infection in my stiches, had running fevers for days on end, got over the infection eventually although how I did I will never know, I was absolutely exhausted, the worst kind of tired I have ever been. When he was 6 weeks the HV helpfully suggested FF, and gave no other advice, not even about expressing (I didn't even know you could express and then feed them later with the EBM) he had one bottle of FF, I actually had a whole 2 hours off feeding, can still remember how good I felt in those couple of hours! When he wanted feeding again, he took his usual amount and then sicked it all back up again, and every time I BF him after that first FF he just chucked it all back out. I was half devastated and half estatcially happy that it was over!
DS2, completely different end of the spectrum, firstly I did have the support of the MW/HV, and even had a BFC ring me within 2 hours of getting home from the hospital to set up a meet and just let me know she was there if I ever needed her advise. As it was DS2 was a dream feeder, we got into a routine within a week, I had no engorgement like with DS1, he would feed for about 10-15 minutes every 2-3 hours. I also co-slept which meant I missed out on very little sleep. We just had no trouble or problems at all! He started dropping feeds in the day at about 9 months, and then slowly it just stopped, he did get to the point where he was waking in the night, not because he was hungry just for the comfort, which at 11 months I stopped doing, I thought he'd go absolutely mad but he just seemed to 'get it' and that was it, we'd finished BF'ing.
Fingers crossed DC3 will be like DS2 because I am not even going to buy bottles or anything 'just in case' DH can always go and get some if we needed them.
