After the recovery she will go home with you if that is the plan. But she may be there with you for a few hours. It's a great idea to make a picture together about the whole experience. Also some hospitals have books which the nurses read to the children before the surgery. You may wish to check your local library for a book about going to the hospital.
Some parents use a toy doctor's kit to play out the experience with dolls.
But not all children take to that and its important not to push it. You can go over some of what we have talked about with your pediatrician- especially about the holding room and the recovery room policy at your hospital. Also whether your child can take her blanket with her to the surgery. Ask whether a visit to the hospital before surgery is possible. Its important to keep in mind that after the surgery, you'll get a second chance to go over what happened with your child and to tell the story again.
