Baby bottles for back to work

How many bottles did you have for your baby after you went back to work ?

I’m about to throw away 6 so now I’m left with 4 decent ones. The other 7 I have are too big as in 8, 9 ,10 oz . Baby is only drinking about 2-4 oz so it’s no point of using them yet. I breast feed so I don’t really use bottles everyday.

Im about to spend about $55 on 8 bottles lol two separate brands & kits. One is 9 piece kit and other is a 3 pk.

I don’t wanna come home and have to wash/sterilize bottles everyday .

How often do you replace bottles & pacifiers ? My baby is 2 months old .
