KINGSPORT — While most kindergartners were working on getting rid of that Halloween candy on Sunday, one was saving his mom’s life.

Melissa Williams was not feeling well on that day. She was sweating and nauseated. On the verge of passing out, she called her fiance and told him he needed to get home. Soon after, she hit the floor.

When she went down, her 5-year-old son, Tommy, picked up her phone and pressed the picture of his father, who he knew would call back. When Tommy told his father that his mommy was sleeping, his dad told him to wake her up.

Tommy couldn’t wake her.

So his father told him to look out the window and see if their neighbors were home. They were. Tommy was instructed to get the neighbors, so he ran to their house and pounded on the door until they answered.

He told them his mom needed help, and the neighbors came over and called for assistance. Tommy’s dad showed up a few minutes later, and Melissa was rushed to the hospital.

She was having a heart attack.

The next thing Melissa remembers is waking up in the emergency room at Holston Valley Medical Center. She had two stents placed in her heart.

Sitting on a hospital bed, Tommy perched on her lap snapping pictures with her phone, Melissa was grateful for her son.

“I had my tubes tied three years before he was born,” she said. “He was my miracle baby. My doctor told me, ‘Your miracle baby saved you.’ ”

Melissa’s heart attack was brought on by a clotting disorder. The same disorder caused her to have a stroke six weeks ago.

Tommy is currently attending Sullivan Gardens Elementary and is working on learning to read. He said when his mom fell down, he was not scared.

Without him being there, Melissa doesn’t know what might have happened to her.

“Thank God he was there,” she said. “He saved his mom. He’s Mom’s big hero.”
