B.H.
I don't know where you live in Las Vegas but here are a couple of suggestions for you.
Little Buddies Clubhouse-this is where my 4 yo currently attends and I LOVE, LOVE it! Most people know her as Ms. Delores. She does the school out of her home and it is so great. It is located in Henderson near the Silver Springs rec center. She might have a waiting list so I would call as she only takes 6 kids in the morning and 6 in the afternoon.
UNLV-they have a great program but also a waiting list. If you are flexible on the time she goes then you might be able to get her into the late afternoon session and when something becomes available in another time slot you could move her.
Hope that helps!
