Found a solution to the kids eating everything in the cupboards. They wanted to make the food; I said ok, but it'll take about 6 hours and since they didn't believe me; we went and bought all the ingredients, then went to work. They were whining after a half an hour of prep and didn't understand the cleanup; which had to be done again and again. They wanted desserts, okay, that takes longer, but I'm game. After 6 hours of working and cleaning and cooking, they were exhausted ( we finally finished at 3am). Woke them up at noon to present their desserts at a family thing. Haven't heard from them since. The desserts rocked; but think they are too tired to even think about asking to come over again for tips.
