Ryan seems to have picked up a few cues from his sister, who currently communicates almost everything by singing. This AM as we drove to school, he sat in the back and played games on my iPhone. While playing those games, he also continually sang "No go school". It was lot better to hear this happier version of a protest than the screaming and crying protests I've had to endure the past couple of trips to school, so I was optimistic.
We pulled up to school and had to wait to get a parking spot. He cheered, "My school!". He talked about the "parking lot" and started counting cars. He noticed a car pulling out and informed me that there was a spot available. As I pulled in, he again informed me "no school" in a slightly less happy tone. However, it was a fairly weak protest and I (again) took it as a good sign.
We got into his classroom and his teachers greeted him. He ducked his head and hid into my shoulder, but soon picked it back up. He was smiling! We washed hands and he gave another little protest. The teacher asked if he wanted to build a tower, he grabbed her hand and took off. Success!
