Is it OK to pierce a baby's or kids' ears?

According to pediatricians, it is perfectly safe to pierce a child’s ears after the age of 6 months. They urge parents to wait until immunity has strengthened in order to prevent infections.
 
Here are some tips about ear piercing with babies and small kids.
 
Be prepared to keep things clean
Know that the younger you pierce your child’s ears, there’s more work involved for you. It’s imperative you rotate the earrings in the earlobes and keep things clean to avoid infections.
 
It’s going to hurt
Babies will scream, but like shots, will soon forget the pain. However, you should be careful that your baby won’t pull out the earrings.
 
Choose the right kind of earrings
Gold and sterling silver earrings have the least chance of causing irritation and infection. Stick to those types of earrings first.
 
Avoid dangling styles
Once you can change out the earrings, don’t get dangling earrings that can snag easily while playing.
