How many millimeters should a baby earring be?

The size of baby earrings typically ranges from 3mm to 6mm in diameter. Smaller earrings, around 3mm to 4mm, are generally recommended for infants and younger children to ensure comfort and safety. It's essential to choose lightweight, hypoallergenic materials to prevent any irritation or allergic reactions. Always consult with a pediatrician or a professional piercer for specific recommendations based on the child's age and sensitivity.
