Thank you for the advice. He has done one swallow study but it was done 2 wks after surgery. I have called the speech therapist and asked if we can book a follow up study. His swelling is down and he's much more alert now. We found that wk 3 he was still very tired and would fall asleep in mid conversation. By wk 4 he was up and present. That�s when he began practicing with water and a tsp. Hopefully we can get a second study scheduled soon.
