Oral Thrush in Babies
Oral thrush is a fungal infection (Candida) in the mouth. Typical: white patches on tongue, palate, and inner cheeks that cannot be wiped off. Common in newborns and infants.
Possible Causes
- 1Candida yeast (natural organism that overgrows with immature immune system)
- 2Infection during birth (vaginal Candida infection in mother)
- 3After antibiotic treatment
- 4Transmission via unsterilised dummies or bottle teats
What You Can Do
- Antifungal suspension (e.g., nystatin) from paediatrician — apply 4x daily after feeds
- Boil dummies, teats, and teething rings daily (5 minutes)
- Breastfeeding mothers: treat nipples too (thrush can transfer)
- Continue treatment 2 days after symptoms clear
When to See a Doctor
- Baby feeds poorly or refuses food
- Thrush doesn't clear after 7-10 days of treatment
- Thrush spreads to oesophagus (swallowing difficulties)
- Nappy rash at same time (Candida nappy thrush)
Age-Specific Notes
Most common in the first 2 months of life. Can also transfer to the breastfeeding mother's nipples (stinging pain during feeds). Check nappy area simultaneously — thrush can appear there as nappy thrush.
