You are the mom who took her misbehaving child out of the restaurant to correct his behavior. You told him in no uncertain terms what behavior was acceptable and that if he wanted to go back in and join the family, he would need to change ASAP. You stayed with him until he acquiesced, albeit reluctantly. When he started to whine a little, you shut it down. Mom, you did a great job. Thank you for providing him with the guidance he needed. He may not have realized it at the time, but he is a lucky boy to have a mom like you.
