Long before primal, we set up a routine where Monday and Thursday are "ice cream nights", and we usually don't have dessert any other night. Maybe that would be a way to transition them away from the idea that dessert is an every night thing?
Or simply don't stock ANY of that stuff. It's now 2 months since we've had any white sugar in the house, and I've no intention of buying any more, even though I'm the only one who is intentionally primal in this house. Maybe Toddler Groklet really really liked raccoon pancreas, but when there simply aren't any raccoons around, I can't imagine that the Groklet kept up the whining for it for more than a day or two!
Zone diet on and off for several years....worked, but too much focus on exact meal composition
Primal since July 2010...skinniest I've ever been and the least stressed about food
