Michael Wells is a Canadian business person who has written a book called "Snapshots of Heaven - 40 Funny, Profound, Real-Life Stories About Children" sharing his wisdom on parenting.
His main point is that we have a limited amount of time to spend with our children or grandchildren and we need to make the most of that time by appreciating all the wonderful things young people bring to our lives.
This is a link to his website snapshotsofheaven.com. The interviews on Canadian television, available on his website, give you a pretty good idea of what he is saying.
The stories in his book are from his own children but he is soliciting stories from other people for a new book he is writing.
