1. Ban pre-party sugar. It’s tempting to waive treat restrictions just before an event, but letting kids snack on sugar makes it harder for them (and you) to manage outbursts and emotions later.

2. Start the day with filling food. Eggs are a good choice, but any healthy food that fills kids up early is fine.

3. Nibble on nuts. They’re high in healthy fats and protein to keep blood sugar steady. Other good slow-burning options include avocadoes, beans, and olives

4. Sprinkle on cinnamon. It’s naturally sweet, and a number of studies have shown it can lower blood glucose levels. For a sustaining pre-party snack, add 1/2 teaspoon cinnamon to a yogurt-and-flaxseed smoothie sweetened with frozen blueberries.
