The Clueless star became a first time mother last year (11) when she gave birth to Bear Blu, but vegan Silverstone has raised eyebrows with her ""favourite"" feeding technique as she helps the now-10-month-old tot adjust to solid foods.

She has uploaded a video on her The Kind Life blog to demonstrate the tactic alongside a post, in which she writes, ""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!""

Bear Blu is Silverstone's child with her husband Christopher Jarecki.
