So what happens with breastfeeding is that your body produces milk according to the stimulation of the baby feeding.
Ie the more they suck the more your body produces. There are also changes in the amounts of fat/water/protein/immune support and so forth, dependent on thirst/growth spurts etc which is again related to sucking/feeding frequency but also the point you are post partum and biochemical communication between the baby and mother (not fully understood yet).
You have to be careful in the early days (<4m) because firstly your infant may not take the bottle you’ve pumped, and you aren’t producing enough to replace it quickly to deal with the screaming, hungry, child. Secondly by skipping feeds or pumping you can muck up the supply and demand scenario which can lead to dwindling supply or oversupply. Thirdly, your body does not care that you’re out in a nice restaurant and will continue to produce milk - so if you don’t feed the baby or use a hand pump to get rid of the milk you will have explodo tits/soaked top or will run the risk of developing mastitis.
If you have ever heard cows at a farmyard mooing because their udders are engorged and they are uncomfortable (akin to really needing a pee), that is the scenario. It is not that you “want” to feed the baby, it is that you NEED to feed the baby.
Post 4m pumping is easier but not every one is able to continue feeding baby and produce extra. Some are able to produce tonnes extra, some none, I managed a few ounces extra a day and froze them for DH etc to feed baby if I needed to go somewhere without baby. Invariably this leads to oversupply though. You will need a hand pump in your handbag it out without the baby. Stick a waterproof mattress protector on your shopping list for explodo tit night dramas that arise when pumping/weaning.
You don’t need to get the baps out if you don’t want to; there are mother and baby rooms most places and failing that disabled toilets. But mostly after a while you will get over yourself and just get on because after you have a baby and commence breastfeeding, all of your boundaries shift and being precious goes out the window.
