"This world is a better place because she has been in it," Parker said.

Emilie's aunt described her niece as the "sweetest little girl I've ever known."

The family is devastated that "someone so beautiful and perfect is no longer going to be in our lives and for no reason," said Jill Cottle Garrett.

Emilie's father, who works as a physician's assistant in the newborn unit at the Danbury hospital, recalled his last conversation with his daughter was in Portuguese, a language he was teaching her.

"She said that she loved me, and I gave her a kiss and I was out the door," he said.

Jack Pinto, 6

Jack was a first-grader, and his interests ran the gamut -- baseball, basketball, wrestling, snow skiing. But his first love was football, and his idol was New York Giants star receiver Victor Cruz.

Cruz paid tribute to the team's young fan by scribbling "Jack Pinto. My Hero" on one of his cleats and "R.I.P. Jack Pinto" on the other during the team's game with the Atlanta Falcons over the weekend. On his glove, Cruz wrote, "Jack Pinto. This one is 4 U!"

Jack recently participated in his first wrestling match and won a medal, according to the president of the New Milford Wrestling Association.

"In life and in death, Jack will forever be remembered for the immeasurable joy he brought to all who had the pleasure of knowing him, a joy whose wide reach belied his six short years," Jack's family wrote in an obituary for the little boy.

Noah Pozner, 6

"He had a huge heart and he was so much fun, a little bit rambunctious, lots of spirit," Noah's aunt told CNN. "He was really the light of the room."

Victoria Haller said her nephew loved playing with his cousins and siblings, especially his twin sister.

"He was a gorgeous, gorgeous boy and he could really get what he wanted just by batting those long eyelashes and looking at you with those big blue eyes. You really couldn't say no to him," she said.

His siblings don't know yet the exact way in which Noah passed away, Haller said.

"How do you tell them that's how their brother died?" she asked. "It's the unthinkable really."

Caroline Previdi, 6

"You were a sweet little girl and you will be missed."

That's the message that Caroline's aunt reportedly tweeted, saying goodbye to her niece, according to the online version of the Press-Telegram in Long Beach, California.

"It hurts even more to see a familiar name on that list," the report said Paige Tremblay also tweeted.

A Facebook page called "RIP Caroline Previdi -- Sandy Hook Massacre Victim" contains dozens of messages. One reads: "Rest in Peace, sweetheart. I know for sure that God is with you and all the other sweet little angels. I feel so very sorry for all these families who lost their precious kids, my heart goes out to all of you."

Jessica Rekos, 6

Jessica loved everything about horses -- horse movies, horse books, drawing horses and writing stories about them.

She asked Santa this year for new cowgirl boots and a cowgirl hat. Her family had promised she could get her own horse when she turned 10.

"She was a creative, beautiful little girl," her family said in a statement, describing Jessica as their "rock."
