It can be distressing to notice a persistent white film on your baby’s tongue, especially when you are diligent about hygiene. While it’s normal for a baby’s tongue to have a milky residue after a feed, oral thrush is a fungal infection (Candida) that often presents as a 'curdy' white coating that doesn't wipe away with a clean cloth.

Why It Happens

Oral thrush is not necessarily a reflection of poor hygiene. Candida is a fungus that lives naturally in the body, but it can overgrow in the warm, moist environment of a baby’s mouth. It is occasionally more common in infants who use bottles or pacifiers, as these can create environments where milk residue lingers, providing a perfect breeding ground for the fungus.

Recognizing the Signs

Beyond the white patches on the tongue, inner cheeks, or gums, you might notice:

• Irritability or fussiness during feedings.
• Latching on and off repeatedly.
• Your baby seeming hungry but refusing to feed due to discomfort.

What to Do

If you suspect thrush, the first step is to consult your pediatrician. They can confirm the diagnosis and provide appropriate antifungal medication. It is important to complete the full course of treatment as prescribed, even if the symptoms seem to disappear quickly.

Because the infection can be passed back and forth between parent and baby, some doctors may recommend treatment for both the nursing parent and the infant to prevent reoccurrence. Remember, thrush can be stubborn, but with proper medical guidance and consistent treatment, it typically clears up quite well.

Disclaimer: Always consult your pediatrician for diagnosis and treatment options. Do not attempt to treat thrush with home remedies without professional advice.
