THE STORY
Harvey was running as fast as he could.
Around the tree.
Across the yard.
Back to his friends.
“Catch me if you can!” he barked, laughing.
His friends chased him, and soon they were all tumbling in the grass.
Harvey flopped onto his back.
“Whew!” he said.
Something felt different.
Thump-thump.
Thump-thump.
Thump-thump.
Harvey sat up.
“Hey… what’s that?” he asked.
His friend Mateo put a paw on his chest.
“That’s your heart!” Mateo said.
“My heart?” Harvey asked.
“It’s beating fast!” Mateo said.
Harvey’s eyes got wide.
“Is that okay?”
Later, at home, Harvey went straight to Mom.
“My chest is thumping!” he said. “Is something wrong?”
Mom smiled gently.
“Let’s take a look,” she said.
She placed Harvey’s paw over his chest.
“Do you feel that?” she asked.
Thump-thump.
Thump-thump.
“That’s your heart beating,” she said. “And it’s doing exactly what it’s supposed to do.”
Harvey tilted his head.
“What does my heart do?” he asked.
Mom sat beside him.
“Your heart is a muscle,” she explained. “It works like a pump.”
“A pump?” Harvey said.
“Yes,” Mom said. “It pushes blood all through your body.”
“Why?” Harvey asked.
“Because your body needs oxygen and nutrients to work,” Mom said. “Your blood carries those things to every part of your body—your muscles, your brain, even your toes.”
Harvey wiggled his toes.
“My heart sends things to my toes?” he asked.
“It does,” Mom said, smiling.
Harvey thought for a moment.
“But why was it beating so fast?” he asked.
Mom nodded.
“Great question,” she said. “When you run and play, your body needs more oxygen and energy.”
“So my heart works harder?” Harvey asked.
“Exactly,” Mom said. “It beats faster to send more blood where it’s needed.”
Harvey sat up a little taller.
“So my heart was helping me run?” he asked.
“It sure was,” Mom said.
“Can we try something?” Harvey asked.
“Of course,” Mom said.
Harvey placed his paw on his chest.
Thump-thump.
Thump-thump.
“Now I’m going to run in place!” he said.
He started running.
His ears bounced. His tail wagged.
After a few seconds, he stopped.
“Now feel it!” Mom said.
Harvey placed his paw on his chest again.
Thump-thump-thump!
Thump-thump-thump!
“It’s faster!” Harvey said.
“That’s your heart working hard,” Mom said. “And that’s a good thing.”
Harvey smiled.
“My heart is strong,” he said.
“And every time you move your body,” Mom added, “you help make your heart even stronger.”
Harvey thought about all the things he loved to do—
Running.
Jumping.
Dancing.
Playing with friends.
“I’m going to keep my heart healthy,” he said proudly.
“That’s a wonderful plan,” Mom said.
That night, as Harvey snuggled into bed, he placed his paw gently on his chest.
Thump-thump.
Thump-thump.
“Good job, heart,” he whispered.
And his heart kept beating—steady and strong—helping him rest, grow, and get ready for another day.
