Can tea tree oil in the bath tub help clear up a yeast infection in a baby?

Tender Skin. Babies have tender skin and tea tree oil may cause more irritation than it relieves in babies, infants, and toddlers.
I wold not do this. In a baby, i would avoid this substance. It could be very unconfortable for a baby and there is not reason to do such. There are much better ways to treat a yeast infection.
