Winston's Wish is a specialist bereavement charity which provides a free "Ask Email" service for children of all ages who may need support with a recent bereavement, have any questions about being bereaved, or would prefer not to talk to an adult in their immediate lives directly.
There is a simple proforma for them to complete, but they do require an email address in order to receive a reply. Children under 13 may therefore require support to fill out the form correctly.
