What's your baby really thinking?

Adelaide Antoinette James, 5 months, shows her serious side before going out for a stroll.

"How do I touch that thing that we look at that gives off all that light and heat with the moving pictures? How do I pull that black thing from out in front of Mommy's face that flashes and makes my eyes hurt and see dots?" -- Collin Nguyen, age 20 months, apparently had a lot on his mind.

"Oh please don't let it be more squash flavored baby food!" -- Mia Lockett, age 11 months, has a sophisticated palate.

"Kathy Griffin! Stop picking on Anderson!" -- Jackson Skinner, age 10 months, just before demanding his parents switch from CNN to New Year's Rockin' Eve with Ryan Seacrest on ABC.

"Be afraid. Be very afraid." -- Brooke Bradshaw, age 2, after moving all of the kitchen chairs into the living room and carefully placing a doll on each chair. Mom, Lauren Bradshaw, admits there's "something a little creepy about this photo bomb."

"What?! You want me to work overtime?!" -- Ethan Fox Chau, age 4 months, at the end of a long week.

"High five! Hey, don't leave me hangin' here!" -- Lydia Brown, age 1, couldn't get any takers for a high five at her first birthday party.

"Push-ups are harder than I thought. Please, Mom, flip me over." -- Rick Cordsen, age 6 weeks. He's 35 now, and still isn't a fan.

"Just like Mommy" -- Tess Barret, age 18 months, liked to put her baby to bed before going to sleep herself. She's now 14, and still has a lot in common with her mom, like music, shopping, travel ( although she always insists on the window seat).

"I don't know what's happening, but it's exciting!" -- Jaxson Soto, 13 months, was pretty pumped about his first train ride through Brackenridge Park in San Antonio, Texas.

"Hey Mom ... I am picking some fresh greens for salad today" -- Rhea Purohit, age 9 months, forages in New Jersey's Liberty State Park.

"I'm out of gas! Can someone give me a push?" -- Owen Flemming Banks, age 11 months, hopes to get a push from 4-year-old brother, Mason.

"Are my legs made of rubber?" -- Krisi Hernandez, age 11 months, takes her very first step before falling down.

"Who is that beautiful girl? I really need that crown." -- Sofia Mulder, age 2, loves looking in the mirror, but she never realizes it's her.

"I didn't do it ..." -- Derek Mestas, age 16 months, always clasps his hands or puts them in his mouth when he gets caught doing something naughty -- like pulling all of the clothes out of Mom's dresser drawers.

"They think I'm a celebrity" -- Daniela Rodriguez, age 10 months, graciously handles a gaggle of family photographers on Christmas Eve.

"Wow, my day was exhausting!" -- Poor Evangeline Monaco, 4 months, could barely lift her head to finish a meal.

"Pop! Goes the Weasel. I don't know why that's so funny... It just is!" -- Wilson Kinder (son of AC360 producer Gabriel Kinder), age 5 months. We hear ya, kid!

"Bows are NOT my thing, Mom!" -- Sidney Esser, age 11 months, is not amused.

• Tune in to AC360° this week for a special on babies' brains


• Think you know what's on your baby's mind?


• Send a photo and caption to iReport!

Tune in to AC360° Wednesday, Thursday and Friday night at 8 p.m. for a three-part series, "Baby Brains: What Are They Really Thinking?" Anderson Cooper digs deeper into the subject in a Google+ Hangout with CNN Digital Correspondent Kelly Wallace along with Paul Bloom author of "Just Babies: The Origins of Good and Evil." Click here to watch.

(CNN) -- Dawn Soto often looks at her toddler's expressive face and tries to decipher his inner monologue. She wonders, "What goes through their little minds with all these new experiences?"

Any parent of a young child imagines what their baby is thinking about. Recently, Anderson Cooper traveled to the Infant Cognition Center at Yale University where he watched babies take part in a series of tests aimed at answering the question: "Are we born knowing right from wrong?" He explores that question and other aspects of babies' inner thoughts in a three-part special this week on baby brains.

In that spirit, iReport invited parents to share photos of their babies and guess what they were thinking at that moment.
