Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the symptoms of gasping for air in your 4 year old grandson during early sleep for the last 8 nights.
Your child might be suffering from obstructive sleep apnea.As air flow stops during a sleep apnea episode, the oxygen level in the blood drops. The brain responds by briefly disturbing the sleep enough to kickstart breathingâwhich often resumes with a gasp or a choking sound.The risk factors for obstructive sleep apnea esp. in children include certain physical attributes, such as having a thick neck, deviated septum, receding chin, or enlarged tonsils or adenoids. Allergies or other medical conditions that lead to nasal congestion and blockage can also contribute to sleep apnea.
You must consult your pediatrician for the definitive diagnosis and treatment as the same cannot be made online.
Hope this helps. Take care.
