Personally I don't think its right, we took our daughter to a party one time and there was a young lad of about 2 years old with piercings, gold chain the lot. Our daughter was drawn to them like a magpie and it was only a matter of time before she grabbed hold of them and tried to pull them out as most 2 year olds seem to do. The enivitable happened, although another child grabbed hold of the ear ring and pulled it out. Thought it a bit unfair on the lad really. My wife hasn't got pierced ears, so it might rub of on our daughter, although I doubt it.
