The main way to determine whether the quilt covering the baby is appropriate is to observe the baby’s state. If the baby’s body sweats and sleeps uneasily, it proves that the quilt is too hot. If the baby’s hands and feet are cold, it proves that the blanket is too thin. The baby can’t tell if the blanket is appropriate because he/she can’t speak yet, but the family can judge from the baby’s state. If the quilt is appropriate, the baby’s state is relatively peaceful and the quality of sleep is good. If the baby’s body is sweating and he/she is not sleeping soundly, the blanket is too thick. If the baby’s hands and feet are cold, it proves that the quilt is too thin. The baby due to the body is not fully developed, if the quilt cover less easy to lead to the baby cold, cold. However, you should not cover too much, as long as you make sure that when you cover the quilt, the baby’s body is not sweating, and the hands and feet are warm. It is recommended that a thermometer can be placed indoors to observe the indoor temperature, so as to adjust the baby’s clothing in a timely manner.
