Surgical stainless steel earrings are typically your best bet for new piercings, as this metal is the least likely to cause an allergic reaction. Nickel and cobalt allergies are very common, so avoid these metals when you first get your ears pierced.
In this way, what earrings can you pierce a baby’s ear with?
The AAP recommends using gold post earrings that are small, round, and as flat as possible for your baby’s first piercing. While 14 karat (or higher) gold post earrings are more expensive than cheaper mixed-metal options that may contain nickel, they pose the least risk of causing an allergic reaction.
