Can you ask the girl's mother for some guidance? By age 3/4, most of us have some stock responses for situations like this. I don't have any specific advice since my children's special needs are developmental rather than physical, but I also know that my "action plan" is different from my friend's whose son has the same types of needs. In similar situations, I prefer to be the one to talk to his peers about the difficulties he has, but she prefers to let the teacher do it. Maybe if you ask the mother how she would like you to handle the situation, she can also offer you tips for making the class fun for her daughter and the others.
Hopefully, others will chime in soon with some more specific suggestions.
