Thrush is a fungal infection
The fungal infection is caused by a yeast (Candida albicans) that is always present on the skin, in the sluimvliezen and in the intestines. When the balance of the bacteria and yeasts becomes disrupted, the yeast will grow and cause an inflammatory reaction. Thrush can occur in the baby's mouth, but also on the buttocks. When a mother is breastfeeding there may be thrush on her nipples. The oral thrush occurs mainly in the first six weeks, at 4% of the infants. Oral thrush is often identified by white spots in the mouth (against the cheeks, on the tongue). In general, the baby does not suffer, but sometimes it can be restless.
