Carving pumpkins with your kids is sooo over. According to BuzzFeed, the hottest way to celebrate fall--especially if you're an Instagram-obsessed mom--is by painting a pumpkin on your baby's butt. The "#PumpkinButt" hashtag has spawned more than 16,000 posts featuring babies' naked bums covered in orange paint in the shape of a pumpkin. While lots of moms are having fun with the trend, others are understandably horrified. "Like, I find zero joy in seeing a pumpkin painted on your child's butt. Pass," one Twitter user wrote, while Extreme Mom blogger Gina Fenton writes, "Babies are not chalk boards or blank canvases, for God's sake...Soon enough, Pumpkin Butt will grow into a child with emotions who's capable of independent thought who will more than likely resent the hell out of the artist."
