Walmart has one for like 15 bucks it’s a swaddle that has a little cloth loop to make a bf cover and it’s actually cute too
i just put a muslin blanket over me.
I got one off Amazon that came with a plastic piece for a window so you can peek down and it covers your back too
Honestly once you have done it a few times you will see you don't expose much and don't need one. However we did use a muslin here and there and just tuck it into your bra strap and pull over baby that way xx
