Hun, I guess it depends where you want to go with it. It's really hard for health professionals, because most mums would like to be told they only have to feed 4hourly. But, that's just not the way the system works. For the first few days mothers make colostrum, which is low in volume but high in all sorts of "goodies" for your baby. Babies are not "hungry" in the way we know it, they are born with stores of brown fat. However, they are biologically coded to know how to make your body make more milk - and that is to feed very often! The night of day 2 or day 3 can be a bit crazy - they often want to feed "all the time" - it doesn't mean you don't have enough milk, and their feeding will get your milk in. But, it can be tough going when you are recovering from a birth as well.
Many times mums say they want to breastfeed, but they do things that the evidence shows will lead to premature weaning. That's fine if you are Ok with that. (and it sounds like you are) but many women express disappointment later on that the consequences weren't explained to them. That they didn't understand that it is more likely that 4 hourly feeding and topping up with formula will lead to early weaning. And theat they are not told what they could do to increase their milk supply - so you see the quandary health professionals are in? some mums are able to breastfeed on a four hourly shedule, but for most mums that's not the case. Your baby is very young. It is easy to think "she always does this' or "she always does that" - but at this age, regardless of how she feed, every day will bring something new. Most of us adults don't feed 4 hourly, and ultimately most babies don't either.
Whatever you decide to do, have confidence. If you ask for information on how to breastfeed successfully, and people give you the information, they are not "having a go', just giving you the information you asked for. There are no gold stars for having a routine. I think that your M&CH nurse could see that you were very close to being able to fully breastfeed and was trying to offer good advice. There are many ways of feeding a baby/many ways of bringing up a baby, and they all work fine. If breastfeeding is not for you, no need to apologies or feel defensive.
