Celebrity moms: Some of their parenting practices raise eyebrows

(CBS News) Celebs are just like us, right? Not always. In honor of Mother's Day, we dug up some of the not-so-normal things celebrity moms have done through the years.

Eating your own placenta? Mouth-to-mouth feeding? See how Hollywood moms chart their own motherhood paths.

Katie Holmes: Katie Holmes and Tom Cruise's daughter, Suri, has been sporting heels and makeup for as long as we can remember. The move sparked some debate over whether young kids should don high-heel shoes.

Now 6-years old, Suri definitely charts her own fashion path. "She'll really tell me [what she thinks]," Holmes told Elle. "Like today I'm wearing brown suede pants, and she said, 'I don't like your pants.' But then she'll say, 'You've got to wear these shoes.' Or 'That's so pretty, Mom. Wear that.' She's got a great eye."

January Jones: The "Mad Men" star told People she gets a jolt of energy by eating her own placenta.

"I have a great doula who makes sure I'm eating well, with vitamins and teas, and with placenta capsulation. Your placenta gets dehydrated and made into vitamins," Jones said. "It's something I was very hesitant about, but we're the only mammals who don't ingest our own placentas."

Holly Robinson Peete: During a January 2011 visit to CBS' "The Talk" the actress said, "True mommy confession ... when my kids were babies, when they would be real congested, I used to suck the snot out of their noses ... The pump thing didn't work! I couldn't get a good angle on it."

Mayim Bialik: "The Big Bang Theory" actress, who recently published a book on parenting, is not shy about her parenting ways. In addition to giving birth at home, Bialik subscribes to attachment parenting, which includes co-sleeping. She still breastfeeds her 3-year-old son, and was recently snapped doing so on a New York City subway car.

Alicia Silverstone: The actress had a video go viral this year when she posted a clip, showing her chewing food then feeding it - mouth-to-mouth - to her 10-month-old son, Bear Blu.

"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," she wrote. "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!"

Nicole "Snooki" Polizzi: In March, the "Jersey Shore" member was photographed with a baby stroller in Jersey City, N.J. -- except the pregnant star was wheeling a doll -- not a real baby. Perhaps she was practicing for the real deal? See the photo here.

Angelina Jolie: Lots of attention surrounded the actress and Brad Pitt when their daughter, Shiloh, appeared in photos dressed in boys' clothes.

In 2010, Jolie told Vanity Fair Shiloh dresses like "a little dude," adding, "Shiloh, we feel, has Montenegro style. It's how people dress there. She likes tracksuits, she likes [regular] suits. She likes to dress like a boy. She wants to be a boy. So we had to cut her hair. She likes to wear boys' everything. She thinks she's one of the brothers."

Kourtney Kardashian: In 2010, the reality TV star blogged about what she called a "controversial" topic: co-sleeping with her young son.

"I wanted to talk about something that is a little controversial... having Mason sleep in my bed with me," she wrote. "Some say it's not the best idea for the baby, but to be honest, much like breast feeding, I find it to be an amazing bonding experience for mother and son and I wouldn't have it any other way."
