La hermanita de Jacobo/Jacob's Little Sister

Jacob no longer rides on his father's back. He is now a big brother. He is helping his daddy today, pushing his little sister in a stroller to the park. His little sister is as cute as a button, but my, she is a wild thing! She runs everywhere in the park. Jacob can't take his eyes off her for a minute, running fast to catch her. It's hard! But Jacob knows it's a big brother's job to take good care of a little sister.
