You are so welcome!
It's good to know you are so involved in his care. OSA (Obstructive Sleep Apnea) can cause increased care post-op, and once again...you are on it!
I'm so grateful that you found Mayo Clinic Connect and were able to gain some helpful information for your son.
It must be stressful going through this with him and his autism. Be sure to take care of yourself too. Do you have a support system in place to lean on? Friends, family, neighbor, church, or an autism support group?
