Possibly! Eating foods rich in protein, melatonin, and tryptophan, such as those listed below, may help support better overnight sleep. Try serving one or two of these foods with your toddler's last meal of the day: Milk and cheese; oatmeal; turkey, chicken, and canned tuna; nuts and seeds (particularly pistachios); kiwi, bananas, cherries, and tomatoes.
The timing of your child’s last meal is also important. If dinner’s on the early side (more than 90 minutes before bedtime), consider offering a snack approximately an hour before bed. Keep the snack small and serve a balance of protein, carbohydrates, and fat to keep them full until morning.
