I am a mommy to a beautiful 11wk old baby girl. I want to get her ears pierced. I need to know when it's safe. I don't want to do it too soon. Also, she was a preemie. Born at 35wks. She has already had her 2month vaccinations. Also, when I take her, is it going to hurt her very bad? I plan on nursing her asap after they're done. Any advice? Thanks!
