It's a balancing act for sure, but I do not believe that children should be shielded from grief. Children are smarter than we give them credit for. I'm sure she already knows that something is up and knows that you are not yourself. We can model for kids a healthy expression of grief. It's okay to cry. It's okay to miss someone that you love and who is now gone. It's okay to let it out and move on. If she knew her grandma and she loves her relatives I think it's okay to let her go and be with her family. If it'll upset you too much, then by all means keep her away, but make sure you don't shield all your tears from her. You miss your mom! Your daughter will understand because she would miss you if you were gone.
