Answer: Call your local Children's Hospital and ask to speak with the Pulmonary department. They are the right team to start with. They will have your child do a sleep study. If they determine your child has sleep apnea, they often will refer you to an ENT, who will check tonsils and adenoids to see if removing them might help.I encourage you to ask for a bronchoscopy and a sleep MRI. These tests can tell you exactly what is going on while the child is sleeping. Our 5 year old was diagnosed with sleep apnea at the age of 3. He wore CPAP for about nine months. The sleep MRI determined that his tongue base was too broad and was falling back in his throat when he slept. They did surgery on his tongue and that helped some.Unfortunately it didn't solve the problem enough, and we go back on CPAP this week.Our hospital admits the child 3 days prior to the titration (getting to the right air pressure level) to work with him or her to get used to the mask. We go in Thursday and get home Sunday.Stick with your guns. A parent's instinct is often right on the money. A sleep study is quite simple and there is no reason your ped shouldn't get one lined up for you. Then you have your answer!!
