Is This My Grandma?

When two young children go to visit their grandma in a hospital, the little brother is scared. There are lots of people everywhere, loud machines with flashing lights, and nurses giving shots. Worst of all, Grandma doesn't look like Grandma. The little boy's big sister has visited Grandma in the hospital before, though. Can she help her little brother overcome his fears and recognize their grandma? Suitable for ages 3 to 7 years.
