The majority of the time, Isaiah is an extremely happy little man. Lately he's been showing his happiness by blowing kisses to anything that moves and some things that don't. However, on occasion, he has been known to be quite not happy, as evidenced below.
Here he's reverting to behavior from the summer that we thought we had passed--baths are torture!
And here he's doing therapy, not the source of the current not happy state. The source? We were talking to Grandma on Skype and we lost our connection. This expression is communicating something like, "Where's Grandma? I want my Grandma!"
So, now you have verifiable proof; he's not happy 100% of the time, only about 97%. Well, and in all honesty, he is beginning to realize the difference between getting what he wants and not getting what he wants, which has also produced some tears. As one of my friends says, "It's hard to submit your will."
