Lori, did he cross over with other Webelos? Is he in the same troop with them? Did he get along well with them, and they are understanding of his challenges?

If this is something he wants to do, and he should have made that decision already since he crossed over, encourage him to give it his all for a certain period of time. Remember, he's not in competition with the other boys, he's in this for his own growth and he's the only one to measure that against.
