Just wanted to post a quick update: In the past 2 weeks I've been trying really hard to arrange some playdates for DS and I think it's been great for him. When he's one on one with his little buddies he seems to be doing great and having a good time. We also went to a big Halloween party and he had fun and we've gotten to visit with a few of his preschool buddies outside of school time (at Halloween activities) and that was good to because it seems to be expanding his social circle inside the school a bit. We've also been working on the phrase 'stay with group' in terms of staying with our class or staying with me and his friends at the zoo.
