When my first brother died my niece was almost four. I watched in amazement as she played with her dolls and worked through her grief. She was "Ariel" and had a conversation with "her father" King Triton where she said good-bye to him because she wouldn't see him anymore.

Kids will work through it. They just might need a little coaxing. Don't be so hard on yourself.
