Can fruit juice cause diaper rash?

Yes, fruit juice can potentially cause diaper rash in some infants. The high acidity and sugar content in certain juices may irritate the skin, especially if the juice is consumed in large quantities. Additionally, the sugars can alter the natural balance of bacteria in the diaper area, leading to yeast infections, which can also result in rashes. It's best to introduce fruit juices gradually and monitor for any adverse reactions.
