When her kids asked why she had lines on her stomach, Nicole Snooki Polizzi from Jersey Shore took the opportunity to teach them about postpartum bodies and body positivity.

On Monday, the mom of two posted a photo on Instagram that shows her kids, Lorenzo and Giovanna, looking at her stomach. In the caption, she wrote that they asked where her lines came from, and she had an awesome response.

I had to explain to them that its my tiger stripes I gained when I became their mommy, she wrote.

Polizzi also wrote that both kids couldnt believe how they fit in [her] belly.
