Children at different ages have different perceptions and understandings of death. They have unique challenges and grief reactions. They may not be able to articulate their feelings, which may then be manifested through problematic behaviors in daily lives. For example, younger children may cry more often and demonstrate regressive behaviors. They may have inadequate understanding of death, and may be curious about it and others’ reactions.
