Just got my nose pierced (my 15-year-old daughter and I actually got matching ones), and as a breastfeeding mum, I approached this with care. Making sure my breastmilk supply is always protected is the most important thing to me, so here's the gist for my BFFs if you're considering the same:
I recommend that you wait until you're around 3-6 months postpartum. Why? Well, our bodies are incredibly busy post-birth, recovering and producing milk. Adding the extra task of healing a piercing might be too much, too soon. Plus, keeping an eye on our vitamin and mineral levels, especially iron, is crucial before taking on the healing of a new piercing.
Getting on top of our postpartum nutrition is always important! Side note, that's why my Lactation Shakes are a GAME CHANGER. Basically, I think there are benefits to waiting a few months after your baby is born.
I can hear them now, "Aren't you worried about infections from piercings affecting your baby through breastmilk?"
That's actually highly unlikely. Recent research on breastmilk and maternal infections shows that most maternal infections don't pass through breastmilk, and it's very unlikely to affect your baby even if it did.
For me, these two points were enough for me to feel comfortable with getting my nose pierced at 12 months postpartum. My daughter thinks it makes me look younger and I think she older.
Either way we are so happy with it! I just hope I can keep my babies busy fingers away from it when he feeds..
Love you BFF, mean it!
