Give them a chance to talk about their fears and validate their feelings. Offer a simple expression of sorrow and take time to listen. Children are repetitive in their grief. Respond patiently to their uncertainty and concerns. It can take a long time to recover from a loss.
Children are physical in their grief.
Children grieve cyclically. Expect their grief to revisit in cycles throughout their childhood or adolescence. A strong reminder, such as the anniversary of a death, may reawaken grief. Make yourself available to talk. Children need choices.
