Judy....sounds like my bus ride twice a day...everyday....LOL. Sometimes I can ignore it and other times I have to get in their face and tell them to calm down or we'll take a stroll to the office. That usually helps. Not sure what you could do in your circumstance though. Me....I'm from the old school and if mine was going to act up and cry....I gave him something to cry for, if you get my meaning.
Good thing they grow out of it just hate that they grow out of the other stuff too. {{{{HUGS}}}}
