My grandson throws things when he is told "no" or doesn't get his way about something. Unfortunately, his parents are not on the same page for parenting. He's also into throwing tantrums, will throw his food, plate, etc. I've always used the "three strikes" theory. After trying alternative discipline, and when he was about to throw his entire plate, I very gently slapped his hand. He put the plate down, cried, but then came over and sat on my lap when let out of the highchair. I'd love for part of this site to be dedicated to the predicaments of Grandparents of grandchildren who are not disciplined by their parents. My six year old Grand-daughter has blown the light tap on my Grandson's hand into a major "beating". It was no such thing, but exaggeration runs rampant with my Grand-daughter. So, how would you (or your child's grandparents) handle the recurring throwing tantrums?
