At the first hint of digestive difficulties, girls stop eating to avoid vomit. They would rather sleep on the bathroom floor than have an accident in their bedroom. Girls will quietly play or watch a cartoon between naps. The first sign of recovery is the girl changing from pitiful to cranky. Even when they feel better, girls have to be enticed to start eating again.
Boys never stop eating. They don’t care if they just puked. They still want to keep eating. When that food gets rejected, boys just explode like a volcano with little or no attempt made to get to the bathroom. Boys won’t settle down for a nap, they just crumble in a heap on the floor for a few minutes before bouncing back up again. At the first hint of recovery, boys will eat the entire contents of the fridge.
