Little Miss Maple is now a big sister and she's taking it seriously. After meeting her baby sister for the first time, Miss Maple knows there's nothing she wouldn't do for her. She knows being a big sister is not going to be easy, but she's ready for the job. First, she wants to help put the baby to sleep with bedtime stories, and then take her to school for show and tell. Sharing a few of her toys is not so bad after all and taking out the baby's dirty diapers isn't so bad, either.
