Grandparents should have respect for the desires of the parents. I mean, most have the maturity and common sense to realize that every parent has different techniques, and that their children won't parent their own kids exactly as they parented them. I think spanking is a very personal choice a lot of people are not comfortable with, and absolutely no one should just assume they have the right to smack a child who is in their care. They need to receive permission from the parent.
