Thrush

So on our second round of nystatin for trush! Ugh I'm so annoyed! Luckily it doesn't seem to bother LO and i just have a little bit of pain but it's just so annoying and time consuming!  This isn't how I want to spend the last month of my maternity leave. I'm santizing and scrubbing everything daily. I've read some things about grapefruit seed extract and probiotics but I'm hesitant to try those things because I don't want to cause any harm. Anyone had any luck? My LO is 7 weeks
