Alicia Silverstone thinks it's "adorable" when she chews her son's food for him.

The 'Clueless' actress recently revealed her unorthodox method for feeding 11-month-old Bear - which involves chewing food then spitting it into the youngster's mouth - and says she can't believe the uproar it's caused because it is a natural way to feed babies.

She said: "People have been feeding their kids that way for thousands for years. It's a weaning process. Honestly, when I posted the video I was not thinking, so maybe I was like Cher (her character in 'Clueless')! I think it's adorable and it makes me laugh every time he does it.

"He attacks my mouth and I think it's adorable. He also knows how to use his hands and he also eats regular food so when babies are weaning, he still breastfeeds. Some people think that's disgusting too which is insane."

Alicia insists she and her husband Christopher Jarecki weren't trying to tell people how to raise their children when she posted the video, but say it's a routine they feel comfortable with.

Speaking at an audience Q&A with director Amy Heckerling following a screening of 'Clueless' and her upcoming film 'Vamps', Alicia said: "It's just a thing that has been going on for thousands of years and I didn't think I was inventing anything but in our culture...

"Every time my husband goes to the YMCA some guy comes over and says, 'That's how we do it in the south!' Between him getting those great comments and me knowing in my gut it's natural and lovely, I really wasn't trying to tell anybody what to do."
