If the baby falls asleep with a cough, parents can try to take the side of the way, and secondly, if there is still coughing during sleep, it is recommended that the baby will be picked up and patted on the back to alleviate the symptoms. If a baby falls asleep with a cough, there may be thick phlegm in the throat, so parents should try to put the baby to sleep in a side-lying position, avoiding lying on the back, which may cause suffocation and jeopardize the baby’s life. In addition, if the baby falls asleep with coughing, accompanied by obvious coughing, parents can pick up the baby, moderate patting on the back to relieve the symptoms. In addition, we need to pay attention to bring the baby to the hospital for examination in a timely manner, after the cause of the cough is clear and active symptomatic treatment, so as not to delay the baby’s condition.
