If you do not want to do the chicken exit you can go through the queue with her and ask to wait in the child swap area once at the end while she rides. I suggest this, because if you prefer to go through the queue and stay behind at some capacity, especially if she may even feel more comfortable also walking out of the ride with you that would be the way to go. Typically the child swap area is obvious once getting off an attraction, but just in case, she can always ask a TM to direct her to it and from there you can walk out of the attraction together.
