Sure, you can get a piercing while breastfeeding, but it's important to consider a few things.
There's no specific research that directly links piercing to any harm while breastfeeding. However, the importance of hygiene can't be stressed enough to avoid infections, especially in this period when your body is adjusting to new demands.
If you're thinking about a nipple piercing, you might want to pause. It could potentially lead to complications like blocked milk ducts and infections, which wouldn't be great for you or your little one.
On top of that, your body is already doing quite a bit of work recovering from childbirth and maintaining breastfeeding, and the added stress of healing a piercing might be too much all at once. So while it's not strictly prohibited, consider whether this is the right moment for that new piercing.
