Welcome to Neuro Talk. Children are so smart. They pick up on things so fast. I don't think any age is to young to gently talk about MS. My children knew very young, that I was having some trouble. My son grew up to be a OPTA, involved with the elderly. I think this gives your child a chance to learn compassion first hand. Love conquers all, and it will between you and your child. They know anyway, and softly spoken truths go a long way to ease a childs fear. I wish you all the best Andy, I will keep your family in my thoughts and prayers. ginnie
