So glad to hear you are nursing pain free!
Yeast is so persistent and it can be difficult to get rid of. If I were you I'd push for treating baby along with you. And it would be worth it to make the effort now to rid it from your environment as well- washing sheets and bras and towels and things like that in hot water with vinegar or bleach, sterilizing pacifiers and pump/bottle parts if you use them. Here is the LLL fact sheet on dealing with thrush. Lots of great info there.
“We are not put on earth for ourselves, but are placed here for each other. If you are there always for others, then in time of need, someone will be there for you.”
