Do babys get thrush because of dirty bottles?

Babies can develop thrush, a fungal infection caused by an overgrowth of Candida yeast, but it is not solely due to dirty bottles. Factors such as antibiotic use, a weakened immune system, or an imbalance in the oral microbiome can contribute to thrush. While maintaining clean feeding equipment is important for overall hygiene, thrush can occur even with proper bottle sanitation.
