I'm going to suggest something to you and you may want to try it. Instead of pointing out that he's eaten or given the children something that you are planning to use the next day or so...just be quiet about it. Sometimes, when we do not react to their childish behavior, they will stop. The more you react, the more negative attention you are giving him. I know it's difficult, but you've got to step back just a bit and count to ten before reacting to his childish behavior. They do not care if the attention is positive or negative just as long as they are receiving it.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
