The joy of a Grandfather and his grandson, my Dad and baby. So happy to have a Dad still here with his grandson and laughing together. The baby will not remember this moment, but a photo will help him to know, it did happen.
This moment does happen in most of our lives, we just do not remember it, now there is ease of photography, to help.
In most cases, be grateful for your Grandparents, this moment is probably in your past also.
