Last May Clara spent most of the month looking like this:
We eventually discovered that she had a dairy allergy, changed her diet and she stopped looking quite so sad and pathetic.
A whole year later there have been so many changes – she walks, she talks, steals toys from her sister, helps feed the dogs, cooks with me, throws objects in the toilet, identifies poop in any location and no longer has that sad and pathetic look about her.
Nope, now when we have days of extended screaming for mysterious reasons she just looks mad.
What a difference a year makes!

Clara, please tell someone what is bothering you. With words.
I read Clara your comment: She responded with her current favorite word – NO.
