Thanks for all your replies!!! That article was very interesting, I forwarded it to the mother, she hasnt read it yet and was not too keen on the gluten thing but she agreed to read it when she'd have a minute. Just to clarify, I'm used to normal impatience, tantrums and screaming and such, I'm here because I truly believe that the intensity of these screams/fits are beyond normal. My husband and a few family members or neighbors that have been in or around my home during daycare hours have agreed on this matter. That being said, this is difficult for me because she has yet to be abnormally physically aggressive towards the other children and there are moments when this child is the greatest child I've ever cared for AND her parents truly ARE amazing and have been cooperative and working with me to try to find a solution since the beginning but this week I am starting to have more comments like "well she's not like that at home at all so I don't know what else to tell you" so I think I may be starting to get on their nerves about it...both the parents and I have agreed that we will try it for a few more weeks because we do know that she's happy with me and today she was the perfect little kid, no personal bubble or anything...ahhh I wish she could just tell me whats going on
