Try to answer them clearly and honestly. The person who dies loved the child. There are many grown ups who still love and will take care of the child. It's fine to have many different feelings - even anger is okay. It's okay to play and have fun too.
Children deal with grief in their own way.
Feelings may show up in behavior. One child may become clingy or demanding. Another child may have trouble sleeping. This is a common problem if the child was told that death is like sleep. Some children cry.
