My kids are 8 and 5, and I just started doing ‘snack boxes’. Every morning, I put a variety of things in their box – pistachios, small turkey sticks, organic fruit pouches, rice cakes, etc. and usually a ‘treat’ like organic gummy bears. If we have muffins in the freezer I’ll sometimes include those as well. Then, throughout the day, the boys don’t even have to ask for snacks. They know if they’re hungry, they can get anything out of their own snack bin, fresh fruit, or cut up veggies from the fridge. It helps me decide once for the day, and I magically don’t hear ‘I’m hungry!’ every 4 seconds (which is THING haha).
