What’s Inside a Sibling Grief Box? Each Blessings for Barrett grief box is thoughtfully created to give grieving children tangible ways to process, express, and navigate their grief. Boxes may include a grief-focused book, creative project, fidgets and sensory items, a grief coloring journey, comfort items, and other age-appropriate resources. Every item has a purpose: to create space for big feelings, encourage healthy expression, provide comfort, and remind grieving siblings that they are seen, supported, and never alone.
