Havent read any other responses yet, but i dont think she is to old, and they have saftey backs, and it was hard for me to pull my daughters off, so i think she should be fine, i got both my kids dont at claires, at the mall, they were alot smaller though, both 2 months, but BE prepared, my girls are 2 and 3, they have to wear earings everyday, and tehy take them out at night, and they refuse to wear the same pair the next day. ( my 2 year old picks up on my 3 year old) they have way more pairs than me.
EDITED: for all those who says its your childs decisions. obvisouly this lady is asking a question becasue she already knows she is going to get her babys ears peirced. So she didnt ask about your personal feelings on life, and how you raise YOUR kids, she was asking a simple question on if her age was too young, not to do it or not. SOOOOOO..... huh AND they are not TACKY, they are adorable, their babies.... OMG get over yourself, i got my ears periced at 6 months... my sister, my mom didnt get hers done, she was so jealous of me, but too scared, and she waited till she was 13 years old, she cried more than my daughter(2 months at the time) and her holes are not in the right place... She was so mad at my mom for not getting them done at a younger age.
