Jesus said, “Let the little children come to me, and do not hinder them, for the kingdom of heaven belongs to such as these.”
(Matthew 19:14)

We can learn a lot from the children.  They have an innocence that it priceless.  Often children say things so bluntly that it takes us by surprise, but usually, it's exactly what we were afraid to say ourselves. 
Don't just assume that because someone is very young that they don't know what's going on......they usually do understand and have an unbiased viewpoint that is worth paying attention to.  Bless the little children!
