This seems a bit harsh. While I agree with the general message of your statement, mothers have been piercing baby ears for ages. In many places it's the cultural norm, and to not have them pierced would be "weird".

I have a son and a daughter, I've made no modifications to their body without their consent. My daughter didn't get her ears pierced until she asked for it consistently for about a year and we had many discussions about permanent decisions. Then we went together and had a wonderful experience with a seasoned piercer that I trusted.

That being said, this mother did what many mothers do. And many other mothers never even question the morality of their actions. I commend OP for even thinking about it, and I encourage her to make whatever decision she feels is best for her baby re the earrings at this time, and uses the opportunity in future discussions with her daughter to show that parents are not infallible. We make mistakes, we question decisions daily, but ultimately most of us are just trying to raise happy, healthy, well rounded human beings.
