If the kids and a parent were home when the truck came they got an ice cream. They were allowed seconds once a week. I never thought about how the other kids were treated by their parents. But given our kids behaved I didn't think an ice cream was spoiling them. I don't consider it an entitlement. Anything our kids had could be removed at any time. Entirlements aren't removed.
Given their conduct growing up there was little need for discipline. My daughter never made a mistake in judgement beyond ending up in a timeout chair as a toddler. My son made one mistake when he was thirteen. His penalty was so much more severe than all of his friends he learned he better not misbehave. In fact, it was so much more severe I paroled him a month early for good behavior.
But getting back to the ice cream, the point is decisions have consequences and he learned it at an early age without a damaging effect. For reinforcement he got hammered by the philosophy at thirteen.
