In a new parenting manual, penned by '90s teen queen Alicia Silverstone, the actress has sparked outrage over her bizarre and controversial parenting tips, including her denouncement of diapers as "pseudoscience."
The Kind Mama: A Simple Guide to Supercharged Fertility, a Radiant Pregnancy, a Sweeter Birth and a Healthier, More Beautiful Beginning states parents who force their children to sleep on cots rather than in the family bed are neglectful and declares vaccines unsafe.
The Clueless star has plenty of advice for expectant mothers as well, recommending a vegan diet to "help prevent or cure" a whole range of issues including PMS, insomnia, allergies and weight struggles.
She also shares a placenta smoothie recipe and claims women who are experiencing fertility issues should stop using tampons because of the "potential pesticide residues from non-organic cotton."
The 37-year-old based the manual on her experiences raising two-year-old son Bear Blu and it isn't the first time her strange techniques have raised eyebrows.
Alicia once uploaded a video of her chewing baby food before feeding it to her son from her mouth, much like a mother bird would feed her babies.
While critics found the practice unusual, they take more offense from the actress' book, which many claim presents false and inaccurate information.
Alicia isn't the first celebrity to make waves with her parenting strategies. Here are four more celeb moms who've left critics scratching their heads!
The Big Bang Theory star — who has also written her own book entitled, Beyond the Sling: A Real-Life Guide to Raising Confident, Loving Children the Attachment Parenting Way — revealed she lets sons Miles, 8, and Frederick, 5, sleep in her bed every night.

The Brazilian model has received backlash over her comments about bottle feeding. "I think there should be a worldwide law, in my opinion, that mothers should breastfeed their babies for six months,” the 33-year-old claimed, questioning mothers who feed their children "chemical food" instead.
