Definitely learn how to feed in public. It's so rare now for anyone to say anything - I sat in the middle of a park today Bf my very wriggly (but desparate for milk after a beaker of cows milk, 4 falafels, cheese cubes, peas, an organix bag of crisps, and 3 mini cakes
) 16Mo DS today and I swear no one noticed. In 16 months of BF not one person has even batted an eyelid let alone expressed displeasure about me BF (and it's a good job because I'd be telling them to piss off!).
If you're confident with feeding out and about as long as you have a couple of nappies you never have to go home. I travel around a lot and it was so reassuring knowing that if I were to break down/get held up etc. I wouldn't have a screaming hungry baby on my hands.
The early days are hard because they do feed a lot, but I used it as an excuse to watch loads of box sets, read books etc. (hard if this isn't DC1) and if I was out and about, I used it as an excuse for a cup of tea and a chocolate bar every 2-3 hours.
It really won't be long until you're in town one day (this happened at about 16 weeks for me, but my supply was slower to build and establish) and you suddenly realise they haven't fed for 4 hours and they're still not screaming. It's at this point that you just feel so thankful for the extra £100 a month in your bank account and no sterilising to do.
Well done so far, and whatever you decide your baby will be fine :)
