Often children need to develop a good routine, and what they eat to promote sleep has little effect. Children are more energetic during the day, and sometimes they are overly excited or emotionally stressed after playing during the day, which can lead to restless sleep and poor sleep quality. To ensure a good night’s sleep, you need to pay attention to creating a comfortable and quiet sleep environment, and establish a regular routine, which will help to promote children’s sleep and improve the quality of sleep. Milk, nut foods, millet porridge, cinnamon and other foods, although containing protein, tryptophan, calcium, iron and other components, has a certain role in regulating neurodevelopment, but after all, the content of the food is very small, so what to eat to promote the child’s sleep is usually no obvious effect. It should be noted that the child should avoid overfilling, overfeeding or drinking too much water before bedtime, which can prevent the child from having difficulty sleeping due to abdominal discomfort, hunger, and increased nighttime urination.
