Oral thrush in babies is due to a yeast infection known as Candida. Candida is naturally prevalent in the mouth and on the skin. However, Candida may cause thrush when it develops out of control. Thrush is often seen in nail creases, diaper regions, and vaginas. Oral thrush might occur since the baby’s immune system is still developing and cannot manage Candida levels.

Another probable cause of oral thrush in babies is the recent use of antibiotic treatment. This is because antibiotics might destroy good microorganisms in your baby’s mouth. These beneficial bacteria generally aid in regulating Candida levels in your baby’s mouth. Candidiasis may arise when there are fewer beneficial bacteria present.

Furthermore, your beneficial bacteria levels may be reduced when you’re nursing and have previously been on antibiotics. This may increase your or your baby’s risk of developing thrush.


Thrush symptoms in babies include:

  • Nursing refusal due to soreness
  • Mood swings, like being too concerned
  • The appearance of redness in the mouth
  • Wiping the sores might result in bleeding
  • Sores on the tongue and in the mouth that are silky and white

Some newborns might not experience any symptoms at all.


The healthcare practitioner will discuss your baby’s symptoms and medical history. They will examine your baby physically. Oral thrush in babies may frequently be diagnosed by examining your baby’s tongue and mouth since these sores are easily identified.


When your baby has oral thrush but is otherwise healthy, your doctor may not recommend treatment. It will vanish on its own. However, if your baby is having trouble eating or is cranky, your doctor will most likely prescribe oral gel or antifungal drops after every meal for ten days.

Moreover, oral thrush in babies is sometimes associated with diaper thrush, which requires treatment concurrently. When your kid has oral thrush, you can still nurse. Your doctor may also advise using antifungal lotion for your nipples, but you must remove it before feeding.

Alternative treatment

Drops containing nystatin anti-thrush medication are an alternate therapy for oral thrush in babies. You apply the liquid to the affected parts of your baby’s mouth with a dropper that comes with the drops.
