A nurse adopts her tiny patient and more feel-good moments that will have you tearing up

Over the last year, there were countless stories that touched our hearts and warmed us to the core.

In honor of GoodMorningAmerica.com's first birthday, here are some of our favorite moments.

PINT-SIZED INSPIRATIONS

Girl in wheelchair can stay warm outside thanks to mom's invention

Zoey Harrison almost gave up on recess because it took too long to bundle up.

But the 9-year-old didn't let her love for the outdoors stop her. When Zoey had trouble keeping warm while sitting in her wheelchair, she asked her mom to make something that didn't take long to put on.

Mom Jennifer Harrison made modifications to two purple coats, which was later named the "Bodycoat." Harrison then created a demonstration video for Zoey's teacher -- to show the teacher how to put Zoey in her coat.

The video was viewed 11 million times and Zoey's mom received hundreds of thousands of requests for a Bodycoat.

The Harrisons names their company, "X-Ability."

"See my ability -- not my disability," Zoey told ABC affiliate WZZM adding, "I saved recess for myself and a million other people."

Zoey's story and her sparkling personality captured the hearts of millions more after being featured on "Good Morning America."

Little boy with a rare bone issue giving positive affirmations is all we need

We all became inspired when meeting 3-and-a-half-year-old Sammy Silver, who gives himself positive affirmations.

Sammy was born with the genetic condition osteogenesis imperfecta, or brittle bones. His mom, Allison Silver, from Brooklyn, Connecticut, told "GMA" he was born with a broken skull and bones and has endured dozens of fractures since then.

Sammy fears medical appointments. Even drawing blood can leave him with a fractured bone. So his mom took to giving him positive affirmations. Now Sammy does them for himself.

In a video posted to his Instagram Strength for Samuel, he can be heard saying "I tough, I brave, I strong, I Sammy Silver!"

3-year-old's reaction to his birthday cake is how we all feel inside

It was impossible not to smile at 3-year-old Rhett Flener's an incredible reaction to his birthday cake.

Though mom Lee Ann Flener expected Rhett would love his purple cake, she had no idea his reaction would be so adorable, or that it would touch so many people, she told "GMA" in January. His adorable video was viewed more than 70 million times on mom's Facebook and 9 million more when "GMA" shared it.

Toddler warms hearts showing his dog he can walk

We can't forget Roman Dinkel, the toddler who spread joy across the globe after a video of him celebrating his first steps alongside his dog racked up millions of views on Facebook.

Roman was diagnosed with spina bifida when his mom, Whitney Dinkel, was 20 weeks pregnant with him. Doctors told the Dinkels that there was a chance that Roman wouldn't be able to walk.

Since then, Roman has persevered and now, he's walking without his crutches.

Nurse adopts sweet baby she cared for in Illinois intensive care unit

Angela Farnan, a primary charge nurse at OSF Children's Hospital of Illinois, stole our hearts after officially becoming a mom to her son Blaze, 1.

Blaze was born with a congenital heart defect called hypoplastic left heart syndrome. He had his first surgery when he was just 3 days old. He needed a second surgery just months later. Farnan was one of the nurses who cared for Blake in the ICU. She said Blake's biological family, who lived far away, did not have the resources to go back and forth to the hospital, or to care for him financially.

Farnan said she took Blaze into her care and had short-term guardianship, with permission from his parents. After his second surgery on March 20, Blaze's birth mother presented Farnan with a tearful request to adopt their son.

"Becoming a parent for the first time, I can't describe the feeling," Farnan said. "It was one of the best days of our lives."
