May marks Shaken Baby Syndrome Awareness Month, a condition that can leave lifelong injuries or worse.

A Greenville couple wants to spread awareness after they refused to let their four-year-old Maggie's future be defined by her past. 

Maggie lights up the room.

Her laughter, her energy and her spirit are a testament to her strength, but beneath her playful smile is a darker beginning.

"Maggie probably will never live on her own," her adoptive mother, Dawna Walsh said, "She probably will never be in a regular class. We don't even know if she's going to talk."

Maggie suffered from Shaken Baby Syndrome when she was just months old.

"When a child is severely shaken, the brain swells tremendously. If something doesn't happen, they die," said Walsh, who was a pediatric nurse before she retired. 

She's partially blind, non-verbal, and has undergone seventeen brain surgeries.

"It does a lot of damage," her adoptive father, Dave Walsh, said.

She is also undergoing occupational physical therapy and has a seizure disorder.

Her development is uncertain, but she's walking, something doctors said may never happen. Most importantly, she'll never be alone.

"We believe in Miracles," Dawna said. 

The Walshs, foster parents in their 60s, took Maggie in at six months old. They said they fell in love with Maggie and eventually adopted her.

"There was nowhere for her to go," she said, "It was us or another foster home, and we loved her too much."

They've filled their home with love, toys, and even a trampoline, but most of all, hope.

Now, they're sharing Maggie's story to make sure no other child endures this.

"If she's ever verbal, I'd like her to be able to say, 'this is how it impacted my life.' Don't do this to your baby. If you lose your temper, walk away," she said. 

They hope to see Maggie use her voice one day to spread awareness, but for now, her laughter says everything.
