Celebrities have a tendency to be a little on the quirky side, but is "Clueless" star Alicia Silverstone’s unique method of feeding her 11-month-old son Bear Blu clever or, well, clueless? 
 
 The actress and animal rights activist posted a video herself feeding her son breakfast on her popular health food website TheKindLife.com over the weekend. 
 
 “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,” Silverstone wrote. “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!” 
 
 The video shows the actress taking a spoonful of food, chewing it, and then passing it open-mouth to her little one. 
 
 Which may not be such a great idea, say some medical and nutrition experts. 
 
 “There are those who think that a mom chewing a baby’s food provides helpful enzymes from her mouth but it doesn’t seem like a hygienic practice. Various viruses and bacteria, but especially herpes virus, may be passed from mother to baby,” Dr. Jennifer Landa, M.D Chief Medical Officer of BodyLogicMD told FOX411’s Pop Tarts column. “These microbes present a challenge that the infant’s immune system may not be ready for. So the practice is questionable for safety, and then, there’s a certain ick factor here that needs to be considered.” 
 
 Dallas-based family therapist Melody Brooke said the bigger question was whether it is appropriate, on a psychological level, for a toddler to be diving at their mom’s mouth for food. Mira Jacob, deputy editor of parenting site Babble.com, noted that while the concept itself isn’t all that unique, it does come across as – odd. 
 
 “A lot of moms chew a portion of their baby’s food; it’s often a very natural transition. But this just looks really funny, like Alicia is making out with her son,” Jacob mused. “There is nothing terribly wrong with it, it just looks really weird.” 
 
 Even JJ Virgin, Certified Nutrition Specialist and star of TLC’s “Freaky Eaters,” was a little freaked out. 
 
 “Sounds like she is taking eating like a bird to the extreme. While this could help predigest some of it as we start carbohydrate digestion in the mouth it could also pass along any bad oral bacteria she has too,” Virgin said. “I think a food processor and a spoon are a better bet!” 
 
 On the flipside, Heather Lounsbury, founder of LiveNaturalLiveWell.com said the Silverstone’s baby would have already been exposed to anything mom might have through being carried inside her and through her breast milk. 
 
 “I'm sure Alicia is brushing her teeth regularly as to not expose her baby to bacteria in her mouth. It is dangerous to try and live in a completely sterile environment, because it's impossible,” Lounsbury said. “And it doesn't allow for the body to fight minor infections so it can fight more serious illnesses it may be exposed to.” 
 
 The interesting feeding approach has generated mostly positive reactions from Silverstone’s blog followers. 
 
 “I had never thought of this before but it's the cutest way of feeding your baby! I have a 7 month old and I think I will try this method...she is always trying to lick my mouth anyways might as well give her a reward,” commented one fan, while another wrote that it was “so sweet.” 
 
 Jackie Keller, executive chef of Los Angeles healthy food company NutriFit still thinks such behavior would be better suited in the wild. 
 
 “I've never seen anything like this – except in the animal world where birds and some other species pre-chew their offspring's food,” she added. “I wonder what benefit there could possibly be to the child and the mom? Certainly there is no scientific literature that I'm aware of that promotes this type of behavior among humans.” 
 
 A rep for Silverstone did not respond to a request for comment. ||||| 'It's a weaning process... I think it's adorable': Alicia Silverstone defends controversial practice of pre-chewing baby son's food 
 
 
 
 No regrets: Alicia Silverstone, pictured on Saturday, has fiercely defended the practice of re-feeding her son 
 
 Alicia Silverstone has defiantly defended her practice of re-feeding her 11-month-old baby son. 
 
 
 
 Speaking for the first time since sparking a firestorm of controversy by posting a video of herself chewing Bear Blu's food before passing it from her mouth to his , the star called the practice 'adorable', adding that it 'makes me laugh'. 
 
 
 
 Ms Silverstone said she has no regrets about publicly portraying how she feeds Bear, her son with rock musician husband Chris Jarecki, even though many medical practitioners say it is unhygienic and can cause bacteria and viruses to be passed from mother to baby. 
 
 
 
 The actress, 35, was asked about her actions at an audience Q&A with director Amy Heckerling following a screening of Clueless and her upcoming film Vamps at the Brooklyn Academy of Art and Music on Saturday night. 
 
 
 
 Asked if chewing her food and then passing it open-mouth to her son was in the spirit of Cher Horowitz, the ditzy character she played in Clueless, Ms Silverstone launched into a lengthy defence of the practice. 
 
 
 
 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! 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. 
 
 
 
 '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. 
 
 'Adorable': The star sparked controversy two weeks ago when she posted a video of herself pre-chewing her son's food and feeding him mouth-to-mouth 
 
 Nothing new: Ms Silverstone says re-feeding has been going on for thousands of years and didn't anticipate the media storm 
 
 'I wasn't saying this was anything somebody should do. I wasn't trying to be independent or cause such a ruckus. I'm very glad that I did it.' 
 
 
 
 Ms Silverstone also indiscreetly implied she first met Richard Lewis, the 64-year-old actor and comedian who plays her older ex-lover in Vamps, when he was drunk and compared him to her grandfather. Mr Lewis has previously admitted to having a history of alcohol abuse. 
 
 She said: 'The first time I ever met Richard Lewis - I didn't meet him, I saw him when I was about 17 years old in circumstances that he would not be happy to have revealed. It's not exciting, he's a very proud sober person. I saw him when he was a young, not sober person.

 'I feel like I loved my grandfather so much. He would be really offended by what I am saying but I don't mean it that way. There was a love. He's obviously not my grandfather's age but that's part of the love. He's a madman. He's a lovable, adorable madman. 
 
 
 
 'When I would be with him, I would be with him a little like - my grandfather was not like Richard Lewis in any way - but I love him. Richard and I had so much fun together.' 
 
 
 
 Vamps, which also stars Krysten Ritter, Sigourney Weaver and Dan Stevens, will be released later this year.

– Warning: You may not want to read (or watch) this while eating. Alicia Silverstone has a somewhat unconventional method for feeding her 11-month-old son, Bear Blu: She chews the food for him, then lets him take it directly out of her mouth. She posted a picture and video of the practice on her website over the weekend, writing, "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." But is the practice safe? One doctor tells Fox News it may not be, since viruses and bacteria can be passed from mom to baby, and plus, "there’s a certain ick factor here that needs to be considered." The deputy editor of parenting site Babble.com notes that the video looks "like Alicia is making out with her son," and a family therapist questions whether the practice is psychologically appropriate. A nutrition specialist sums it up: "I think a food processor and a spoon are a better bet!"
