The actress has posted a YouTube video called "Bear Eating My Mouth", which shows her chewing a mouthful of food before spitting it into 10-month-old Bear Blu's gobbler, and says it's fast becoming the his "favourite" way to eat.
"I just had a delicious breakfast of miso soup, collards and radish steamed and drizzled with flax oil, cast iron mocha with nori wrapped ouside, and some grated daikon. Yum!" she wrote in a blog post accompanying the vid.
"I fed Bear the mocha and tiny bit of vegies from the soup … from my mouth to his.
"It's his favourite … and mine," she wrote.
It's great that Alicia is an animal-loving vegan, but has she taken a bit too much inspiration from the animal kingdom for this strange feeding frenzy? Adult birds chew, partly digest and then regurgitate food for their young.
And while it's easy to laugh at the weirdness of all this, a medical expert told FOX411's Pop Tarts column that the actress may be jepoardising her bub's wellbeing.
"Various viruses and bacteria, but especially herpes virus, may be passed from mother to baby," said Dr Jennifer Landa of BodyLogicMD.
"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," she said.
But Heather Lounsbury, founder of LiveNaturalLiveWell.com, reckons Bear will be alright — as long as Alicia keeps her pearly whites clean, that is.
"I'm sure Alicia is brushing her teeth regularly so as to not expose her baby to bacteria in her mouth," Lounsbury said.
"It is dangerous to try and live in a completely sterile environment, because it's impossible.
"And it doesn't allow for the body to fight minor infections so it can fight more serious illnesses it may be exposed to," she said.
Either way, it doesn't seem like Bear plans on giving up his mumma bird's chewed up food anytime soon.
"He literally crawls across the room to attack my mouth if I'm eating," Alicia blogged.
