My 3-month-old is sneezing a lot—is this normal?

Frequent sneezing in young infants is often perfectly normal and is usually just the baby's way of clearing their nasal passages. If the sneezing is not accompanied by signs of a cold, such as a fever or lethargy, there is likely no cause for concern. Using an air purifier in the room can help if you suspect allergens, but be sure to clean the filters regularly to ensure it remains effective.
