I don't KNOW, but I don't see how it would really help?
DD's thrush lasted longer because I refused to trash my thrush milk that I pumped. There are ways you can google to get the thrush out with boiling, I believe, but it kills so many other things, I refused to do that too.
Does he have any yeasty signs in his private bits?
Anyways, thats all I've got, but I think you could do the same thing with a sanitized nipple shield as with a bottle. But it's also in the milk.
