Death is so hard for everyone, but for kids especially because it's just so far beyond their grasp of what is concrete and tangible.
Everyone has different ideas of what death is and what happens after death. Personally, the way we dealt with it was more to deal with what was within us, and not where Joe is now.
In other words, he will remain forever in our hearts, and as long as we remember him, he is alive for us. Though it's awful that we don't get to see him here on Earth, we have only to close our eyes and remember to feel that love again.
Death is a sad and difficult part of life. One we must deal with though.
We talk to our kids about Joe when they want to. Sometimes we look at pictures and remember things that we did together.
We let them know that we share their grief and pain, and also their love.
We let them know how important it is to treasure the ones we love now so that when they are gone we know that our hearts will always remember.
One other thing that I've learned is that the depth of our grief is a reflection of our love, and while we are in pain, we must also feel similar joy to know that we had an opportunity to share our love with another creature.
Hugs to your daughter. Love comes in so many forms. I'm really proud of her ability to care so deeply for an animal that I think receives very little regard as a pet.
