My heart was breaking..

I have tears just writing this. Today at church I dropped Thomas off reminded the ladies about his Celiac Disease, showed them his snack and went on my way. We are working on potty training Thomas so on the last song I went to take him to the potty. I walked in and he was having a normal snack with the rest of the children! I said very calmy " Oh no.." so sad he saw me and burst into tears, sobbing "I want to go home, I want to go home, that's an owie snack.." I scooped him up, the teachers were extremely apolgetic. I took him outside to the lobby he was still crying, which was making me cry.. Cam I confess something..Sometimes I am so thankful for CD we are healthier, Thomas is thriving and finally growing as he should,it is controlled with diet not meds, usually it is no big deal. But today when he was so sad and scared and with all the stuff happening at preschool it just makes me mad! I just want to keep him at home and home school him to protect from all of this.. He has talked about it several times since we got home."I dont want to go back to church they have owie snacks."It just made me really sad for him.
