So Proud of my Little Boy

Since August I have been working with this little 2nd grade boy that acts like a 3 year old most of the time. It was a big deal today when he danced with the whole class during 2 songs! It was a big deal because we had to work up to that since August so he finally did it. He danced to the months of the year song and a counting to 100 song that was Christmasy with Santa dancing. He also wouldn't listen to me so I went on my break. When I was walking away for break, I heard him starting to cry. That's a 1st for him too. He never cried if I just walked out the door. He was also spitting at me so that is another reason I left. We are making progress one day/month at time. His mother just had a baby boy last week so this might be reacting to that too this way.
