I worked for a family when I worked with autistic children who didn’t do the Easter Bunny or Santa stuff because she was devastated when she found out as a child and never wanted to hurt her kids that way.

I think you have to know your children and how they will react. Did my son loose trust in us for it? No he has always been a truth teller and tries to teach his sister to tell the truth. I don’t think that my daughter will see it as a lie nor be devastated by this. But you have given me something to think about when her time comes to tell us that she no longer believes. I don’t think I’ve told my dad yet. Then again I still believe. ;-}
