The little bird in this book is meant to be a reflection of the Holy Spirit. He shares with your child the promised hope of God's redemption in our lives and our world. This is a hope we can experience even in the throes of grief.
A helpful process to grieve is to recognize the loss in a tangible way. There is a special place in this book for them to do just that. I encourage you to have your child add their picture of their beloved, whether human or animal, then give your child a pencil and let them write a memory or hope for One Day Again in this book, if they can't write then help them. They can draw the picture.
Whether the loss of a parent, grandparent, friend, or pet, this book brings hope during a sad season in a child's life.
