A young girl loves her grandpa so much! When they spend the day at the beach, she holds his hand as they go for a walk, and they build sand castles together. But sometimes, its difficult, because Grandpa has become forgetful. Grandpa's memories are like the tide, Mommy explains. Sometimes, they're near and full of life. Other times, they're distant and quiet. The Tide is a story about families, laughter, and how we can help a loved one with dementia live well.
