Thrush typically clears up on its own in a couple of weeks. Some babies find thrush painful and bothersome, while others don't seem to notice. If you find that the thrush doesn't go away or is painful to your baby, give our Oral Antiseptic Spray a try. This product is an excellent natural first aid that helps against oral infections. Cleaning and sterilizing pacifiers may also help. If you are a breastfeeding mother, let your nipples air dry between feedings to prevent thrush.
