I also don’t know a single person who BFing was actually free for. Every single woman I know who breastfed bought nursing bras, at least a few nursing tanks if not new clothes that made it easier, expensive nipple creams and patches in the early days, breast pads and most still bought bottles, sterilising equipment and some form of pump even if only a let down collecting one.
It wasn’t free but it was way cheaper than formula feeding in more than just cost.
Sterilising equipment you need anyway.
Bought maybe two or three bottles but the rest were given to us (friends and receiving samples)
3 nursing bras but switched to bralettes and soft bras I already own.
Two items of maternity wear, a shirt and jeans that I bought secondhand and donated later, switched to the clothes I already had that were v-necks.
One tube of cheap nipple cream that I used 1/4 of.
Bought a secondhand pump and some storage bags.
Total was probably under £350 spread across two pregnancies.
Add in less stuff to carry around simply to go out, no making or washing bottles, no getting up and leaving the bedroom to go warm a bottle, no need to buy formula which is expensive on its own and just being able to take out a breast and nurse on demand made it much cheaper for me.
OP do what you feel best. If you don’t want to nurse, don’t. It really is your choice/decision and no one should make you feel guilty for it.
