I do agree that teaching manners from the get go is essential with children. However, all kids have their days. My 1 1/2 year old is very well behaved, but if he doesn't have a good nap he goes a little crazy. I have learned that a good schedule goes a long way. You never know what the crazy child in the restruant has been like that day. However, a parent should use that moment as a learning oppurtunity and remove the child from that situation until he/she calms down so he/she knows that kind of thing is unacceptable. Oddly enough, the same can be applied when training your dog.
