Question 1: Hello doctor, my one-and-a-half-month-old baby was hit on the head by a mobile phone. He vomited a lot. He could vomit two or three mouthfuls at a time, and he slept more than before. Will there be any effects? Dr. He Jiexin answered: The child is too young, parents must pay attention to this situation. First of all, as soon as the baby is hit by a mobile phone, parents should calm down the baby to prevent the baby from being frightened and check whether there is any obvious trauma. Secondly, observe whether the baby is vomiting or mentally depressed. If the baby is in normal condition, don’t worry too much. If you continue to cry, vomit, or wake up easily, it is recommended to go to the hospital for further examination to see if there is intracranial hemorrhage. Question 2: Hello, doctor: A 9-month-old baby fell out of bed. The floor is made of tiles. If he lies flat on the ground, which parts will be injured? Will it affect the brain? Dr. Cui Lixia answered: This can only be determined by examining the child. If the child\’s activities are normal, there is no vomiting, and the problem is not major, you can continue to observe. Question 3 Hello doctor! The baby is 50 days old and has a protruding umbilical hernia. He has been crying recently, cannot sleep well, and his voice has become hoarse from crying. Dr. Song Shufen answered: Children with umbilical hernia should be comforted immediately and cry as little as possible. It will heal automatically after one or two years old. If it is not good, surgery will be required. If the crying continues and is severe, go to the hospital to check for an inguinal hernia or colic.
