Was it the cold medicine?

Well, our little Michael Anne has been a wonderful angel at school! Her teacher has given her outstanding reviews and today commented that she can't believe the difference in her behavior.
I'm wondering if she got a week's dose of some of that recalled cold medicine! Whatever it was, or wasn't, I am so thankful that she is doing well. She is a real sweetheart and she makes our lives so full and fun and meaningful. She is a good daughter.
