However, there are individual differences in how long each baby sleeps. If the baby sleeps late at night, parents are advised to let the baby sleep less during the day and sleep longer at night. Parents should pay attention to the baby’s normal sleep time, if the sleep time is too little may affect the baby’s growth and development, try to create a comfortable and warm environment for the baby, such as the bedroom should be dark at night, to avoid the noisy sound on the baby’s sleep caused by the adverse effects. The temperature of the bedroom should also not be too high, try to keep it at about 26 degrees. It is recommended that parents try to keep the child’s sleep time at about 12-14 hours, to avoid the adverse effects of insufficient rest on the baby.
