These earrings are perfect for a toddler.  They are small, but still noticeable.  The fact that they are round on both sides is perfect because there is no post poking them.  It's also good that it screws on, so that you don't have to worry about the backs coming off. My daughter has been wearing these 24/7 for about 3 weeks now and her sensitive ears are fine, so they're definitely gold.
