Yes. Her credits will be adult credits. Credits are pooled by room, not by person; any of you can use them. Most restaurants will allow you to order a children's meal for her. Make sure you say when you order that her meal will be paid OOP and not with dining credits. You might have issues at Via Napoli depending on how you'd want to order, as they don't allow sharing between DDP and non DDP users or even among DDP users. Have heard Tutto Italia is doing the same thing now.
