Until your child is old enough to ask for and CONSENT to pierced ears, understands it will hurt, and about the healing process involved, is competent in helping to take care of them, and keeping them infection free, it's an absolute hard NO.
I hate pierced ears on babies and toddlers... inflicting pain, and altering someone's appearance purely for cosmetic reasons, on someone young enough to not be able to consent to it, is abhorrent. I'm surprised there hasn't been some sort of reform on this, and until the child is of an age to consent to it, it shouldn't be allowed. Not just due to the pain, it's the fact a parent can decide to do something that permenantly alters their child's appearance, before that child can agree to it. It shouldn't be acceptable, why would anyone want to take that decision away from their child is beyond me. My daughter asked for hers to be done at age 9. We spoke about the fact it will hurt, (no point in sugarcoating it) and researched into the healing process, and she understood that she would have to take a great deal of care looking after them to avoid infection, no swimming initially, and having to put plasters over them for p.e etc. She decided she wanted them done, and that was her decision, made with her consent. It was an exciting afternoon out for her, and an experience I'm so glad she got to have through her own choice. Her sister hasn't asked for hers done, and may never ask for them to be done, that will be a choice of hers and hers alone, if she decides she wants to have them done.
