So, we are buying a used BOB from one of my husband's coworkers. In addition to the stroller, he has given us his wife's used breast pump. It's an Ameda Purely Yours pump, and he says it's designed to be used by more than one person. Part of me is skeeved out by that, because I don't know his wife at all and I've read conflicting reports on whether or not consumer grade pumps are safe to share.
Am I wrong in thinking that you shouldn't share them? If I am, what parts would need to be replaced?
