US actress, author and animal-rights activist Alicia Silverstone posted a video online of her chewing up food and spitting it into her toddler son\'s mouth. \"I just had a delicious breakfast of miso soup, collards and radish steamed and drizzled with flax oil, cast iron mochi with nori wrapped outside, and some grated daikon. Yum! I fed Bear the mochi and a tiny bit of veggies from the soup… from my mouth to his. It\'s his favorite... and mine. He literally crawls across the room to attack my mouth if I\'m eating. This video was taken about a month or 2 ago when he was a bit wobbly. Now he is grabbing my mouth to get the food!\" vegan Silverstone wrote in a post accompanying the clip on her Web site. Bear Blu is 10 months old. He is the first child for Silverstone and musician Christopher Jarecki, who married in 2005. The video was posted during the weekend on www.thekindlife.com Silverstone is best known for her work in the films \"The Crush,\" \"Clueless,\" \"Blast from the Past\" and \"Excess Baggage,\" as well as the music videos for Aerosmith\'s hits \"Cryin,\'\" \"Amazing\" and \"Crazy.\"
