Anywhere you want pierced.
You can get the fake studs and body jewelry. You can even get the ones that have the clips so you don't have to be pierced. It is cheap but it works.

A child's airway differs from that of an adult in that the child's tongue is proportionately larger in the oropharynx compered to that of an adult. Also, a child's airway is smaller and softer and more prone to foreign body obstruction. An infant's airway is smaller and softer still and the trachea is usually about the diameter of a pencil.
Go to a professional piercer. It will be virtually painless and will be better for you and your body.
