Regression Question

Thanks for the feedback.

We have been giving him zertek the past week and he is doing much better. Just about back to his old self...Still stimming a lot, but eye contact/interaction is better and he's giving us some creative language again which is good.

We've noted all the things that have changed lately and think its a combination of them:

Allergies, his brother taking foreground, better interaction with brother, etc.

Thanks again!
