Why are one of my nipples soft and the other one is hard

It's totally normal for your nipples to not always match, so one being soft and the other being hard is usually nothing to worry about! Your body is doing its own thing, and lots of different stuff can make your nipples look or feel different at different times.

Okay so, your nipples react to a bunch of things like temperature changes and even how you're feeling. One of them might just be chilling while the other is reacting to something a little more. You might also notice this kind of thing around your period or when your hormones are doing their cycle thing, because hormones can literally affect everything!

If you're noticing any pain or other changes that feel weird, it's always a good idea to chat with a trusted grown-up or a doctor, just to make sure everything is good. But usually, your body just being unique is the reason.
