For far too long and for many reasons children have to a certain extent been encouraged to suffer in silence where bereavement is concerned. I frequently write about the damage ignoring the existence of a loved one who has died can do. Often with best intentions death becomes a taboo subject within a family unit.
As age appropriate for the child concerned encouraging talking about happy memories sensitively helps accept that death is part of life. It also helps keep our loved ones alive in our hearts. Remember that two children in a family will have a completely different journey through their grief too.
Equally, the death of a pet may be the first experience for a child and gives parents an opportunity to talk about death and how to celebrate the relationships we have when people are with us and celebrate their life rather than focus on the illness or the way in which they died.
