Hi A.-
Sorry to hear about your grandma...
One book I always recommend for children understanding death is "The Fall of Freddy the Leaf" by Leo Buscalia...It chronicles death from a nature perspective...and the cycle of a leaf. It is beautifully illustrated...
With respect to a funeral...I found it helpful that some of my kids HAD attended a funeral of a 'distant' relative...it was a learning/educational/teachable experience about death that I hope in some way helped prepare them for the death of my dad...their beloved grandfather...some years later.
Whatever choice you make will be the right one for you...Healing thoughts your way..
Take Care
