Dad is being totally disrespectful, BUT you're giving him what he wants. It's YOUR daycare. Lunch is at 12:30. When lunch is over, it's over. You're not there...you miss it. It's simple. As Inspired By Reggio said, it's not a restaurant. You've warned him enough times, that I'd just go ahead with my schedule. You're allowing him special treatment by waiting for him. You're waiting for him. Why should he stop? He'll stop when you do as you say in stating that he has to be there by a certain time for lunch...
