I suppose 2 or 3 would work. I would base it off of how many times you change your bra between washings.
Thanks for responding,one more thing, how many nursing bras should I buy? Or is good to have?
I actually got mine off Amazon it's a nursing bra by medela. It's soft cup do sometimes poky breasts are an issue lol but it's made v that way so that it has to give to accommodate your breasts filling and emptying throughout the day feeding etc. I ordered my size and I will have enough room to expand with milk I'm.sure I also breastfed my first and I HATED my old bras. This one is amazing I like it better than any reg bra I've ever had! $40 but very very worth it. Also im a 36G so I have limited options.
I ordered mines online from jc penny and got a size bigger.
I got a size that would for me now and if my boobs grew. I bought a regular nursing bra with my first and it was uncomfortable so this time I bought a nursing sports bra. I've heard they are way more comfortable.
I got the same size. they have a good amount of stretch to them so they were all fine for me.
