Thoughts on piercing baby’s ears?

I know this is s somewhat sensitive topic for some but how you you ladies feel about a baby, 4 months old getting her ears pierced. I am up on the air about it. I know some women believe you should wait until the child can make their own choice. And some say they like to have it done young so they don’t remember the pain, etc. I didn’t get mine pierced until after the age of 16. Always asked my mother why she never had it done when I was young. What are your opinions and experiences. Be nice everyone!!
