What age would you let your son pierce his ear?
This is a good questions we need to answer as a parent. The world is not what we think it is anymore.
You boy can pierce his ear whenecer he feels ready.
Explain the pros and cons to him and provided he is okay with it, I'd go for it.
Age is a number and shouldn't matter in this case.
The fact that we pierce our daughters ears when they're babies....infants/toddlers(most parents do)... the gender of the child plays no roles in this.
Some parents would definitely disagree with the above answer and thinks that their son should only pierce his ear when he is no longer staying under their roof.
