It is possible for a 9-month-old baby to have a concussion after falling face down from a height of 83 centimeters, but the specifics need to be determined by the patient’s symptoms.
If a 9-month-old baby falls face down from a height of 83 centimeters, has no head trauma, is in good spirits and has normal consciousness, and also has no symptoms such as vomiting, lethargy, or irritability, it is generally unlikely that the baby will have a concussion, so you can observe the baby for a while, and let him or her rest as much as possible with fewer activities, or take him or her to the hospital for a checkup if you don’t feel comfortable with him or her.
If the baby has nausea and vomiting, very irritable, not easy to pacify and other symptoms, it may be concussion, it is recommended to take the baby to the hospital in time, do head CT, head MRI and other tests, clear diagnosis and active treatment, so as not to delay the condition.
