The child sleeps dreaming and crying, consider the following aspects: 1, calcium deficiency, which can lead to increased neuroexcitability, manifested as restless sleep at night, often dreaming and crying, often accompanied by excessive sweating, occipital baldness, square cranium, etc.. You should go to the hospital to perform trace elements and other tests, give vitamin D and calcium supplements, more sunshine, and give your child more calcium-rich foods such as milk, soy products, nuts, etc. 2. A poor sleep environment, too much excitement before bed or physical discomfort can make your child sleep restlessly, dreaming and crying. When the baby cries, take a light pat or touch the child, give the baby some milk or water, let the baby fall back to sleep, do not immediately pick up and hold and coax, this will be a vicious circle. If the baby’s crying persists and is not relieved by reassurance, take the baby to the hospital for further examination.
