Well, Tyler's been on the Flonase for about  a week now, and it seems to be working.  I only have to give it to him once a day, and he has been having less symptoms.  I also switch to giving him his whole dose of zyrtec (1 teaspoon) in the evening instead of half in the morning and half at night.  I tried this because Kathy said he seems way too tired in the mornings, more than he should be.  S
