I noticed a few white spots in my 3 weeks old son's mouth and my lc prescribed nystatin for him and topical lotrimin on nipples for me. She said that we would start with this and if it doesn't work that we would move on to something stronger. I was just wondering if anyone has had sucess in treating the infant with oral nystatin suspension? I just tasted it and it is really sweet which seems counterproductive when treating yeast?? I had issues with thrush with my first son and ended up weaning prematurely so I just want to make sure that we are doing the right things this time around.
