Gerry you are a dolt. Some "toddlers" deserve a smack on the ****. I've helped raise two grand children
and and a couple of great, great grand children. There are a lot worse things that can happen to kids than a smack
on the backside.
No toddler deserves a smack on the face by a stranger on a plane. Corporal punishment by a parent is a different topic but not the one here.
Also a slap on the backside is also not the same as a slap across the face.
