I have 5 wk old twin girls. I have taken them to the doctor who said they have thrush on their privates. I have also been told they can get it in their mouths. 1 has white build up @ the inside of her cheek and a mark on her lip. I was wondering what I can do to treat this? I also heard I need to treat my breast as well to prevent it coming back or speading. Do you have any advise for me?
