I have an appt. w/ my son's ENT to have him checked for sleep apnea. He snores when he's on his back,but it's not very loud. He just had tubes put in a month ago and has been on Zyrtec for a few weeks for hay fever. He's a nose breather, and his tonsils are fine, so they'll probably check his adenoids for enlargement. He's been very restless throughout the night, and wakes up crying usually at least once a night. He used to be a very sound sleeper. He has been very tempermental due to sleepiness. Do kids get apnea w/o loud snoring? Could sleep problems contribute to his already delayed speech development?
