The ENT did. Kiddo has enlarged adenoids and will have them surgically removed Sept 6th. One of his ear tubes/grommets has fallen out and a tympanogram (a test for fluid and pressure in the middle ear) revealed that he still has pressure in that ear and so the ENT will reinsert an ear tube when he removes Kiddo's adenoids. His other tube, inserted about two years ago, is still in place and doing its job well.
Prayers greatly appreciated, especially on Tuesday, Sept 6th, and I'll write a post after the procedure sharing how it went.
