Nicole "Snooki" Polizzi is teaching her children an important lesson about motherhood.
The Jersey Shore alum shared a photo to Instagram on Monday, where she revealed to her kids -- 4-year-old Lorenzo and 2-year-old Giovanna -- what those "lines" on her stomach are.
"This morning my kids asked why I have lines on my stomach," the 29-year-old reality star wrote. "I had to explain to them that it's my tiger stripes I gained when I became their mommy. They thought it was so cool and can't believe how they fit in my belly. ????."

So sweet!
Meanwhile, last year Snooki and her BFF, Jenni "JWOWW" Farley, received some bizarre parenting advice from Jenny McCarthy!
