Marshmallow

Reach for this book when your child is struggling with the arrival of a new sibling or a second pet, especially if they are expressing resentment about no longer being the only one in the house. It tells the story of Oliver, an established cat who is none too pleased when a tiny bunny named Marshmallow joins the household. Through gentle observation and patience, Oliver moves from hostility and jealousy to a state of tender guardianship. This Caldecott Honor book uses exquisite charcoal illustrations to mirror the soft, quiet shift in the characters' relationship. It is an ideal choice for parents who want to normalize feelings of jealousy while modeling how a new intruder can eventually become a best friend. Its slow, deliberate pace provides a soothing environment for children ages 4 to 8 to process big changes in their own family dynamic.
