What fun! What excitement! What a nuisance. At least that's the way Sister Bear feels. If it isn't being fed, burped, or diapered, it's being dandled, cuddled, or kitchy-kitchy-kooed. Yes, Sister's pretty fed up with the fuss everyone's making over the new baby. Even the dolls make her angry, because they remind her of the baby. Then Sister gets a special homework assignment and, with a little help from wise old Mama, comes to believe that this new baby might just be a nifty addition to the Bear clan.
