Pint-sized patients at Children's Memorial Hermann Hospital forgot about the nurses and needles Tuesday as they anxiously waited to meet the hero who helped bring Houston a World Series championship.

The room erupted when Carlos Correa walked in.

"It's just a great feeling to be able to see the kids, when you get here, they're shy and then all of a sudden they have a big smile, they ask for a hug and a signature," Correa said.

It's been a whirlwind two weeks for Correa and his fianceé Daniella Rodriguez: A World Series win; a viral marriage proposal; a massive parade; and even a trip to Disney World. Now, they're finally back home for a few days.

"I've been everywhere, but this is the most fun I've had," said Correa. "I love kids, everyone knows that, so to be able to spend time with them, to play around with them, take pictures, it's just amazing."

Correa says it was Daniella's idea to surprise the kids Tuesday.

"It's something great," said Rodriguez. "After winning the World Series, people tend to look at the glamorous stuff, but at the end of the day, these people were here to support and I think the kids love that a champion came to visit them at the hospital."

Correa spent more than an hour shaking hands, signing autographs and talking baseball with his smallest fans, and their parents. Every selfie brought a smile to families going through so much.

"It's about using this platform to impact people's lives," said Correa. "You can see on their faces. They smile. They're happy. That fills me. It fills my heart."

But there was one tiny Astros fan that stood out.

"So I heard a big aww from everybody, and I turn back and he's holding a baby," said Rodriguez.

Correa held 11-day-old Zoey.

"I was more nervous than I was in game 7 or at the proposal," said Correa. "I was super careful, but I was so nervous, it was awesome to be able to hold her."

It's a picture and a moment her proud parents will never forget.

"He has good hands," said Nikki Weinlein, Zoey's mom. "I thought he did a good job. Years from now, she'll look at that picture and be excited."

Correa and his fianceé head to his native Puerto Rico next week. While he's there, he plans to host a special fundraiser for the people of Puerto Rico.
