Cleaning baby's mouth,anyone?

My daughter is EBF and I've been having repeated thrush,affects her too. At first I was given a compound cream to use on the nipples and Nyastin for the baby. I used reusable nursing pads at 1st but using disposable ones now. Doctor once mentioned that I should be cleaning her mouth too.

Anyone else cleaning baby's gums/mouth? How do you do it? Any recommendations on stuff to use? And how to prevent recurring thrush?

Thank you.
