If there are other children in the family, try to involve them in discussions about the funeral to help them feel included in this important event. If they are offered the option to attend the funeral or a special goodbye, they might like to contribute a favourite song, poem or reading. So long as they are prepared for what they will see and hear, most children find it helpful to attend the funeral. Even very young children, toddlers or babies can go to a funeral. They may not understand what is happening now, but when they are older they will be pleased that they were included.
It may also be helpful to ask another adult who is close to the children to help support them if they choose to come to the funeral. If a child does not want to go to the funeral, reassure them that this is OK. Perhaps they could join the gathering afterwards, or you could do something special together to remember their brother or sister who died.
