Before giving your device to your daughter, I would suggest that you perform all the steps provided in this support guide, keeping in mind that this guide informs you how to erase all content of that device, so that your daughter gets a "new" iPhone. So, if you have your data on that device, make a full backup before proceeding, and don't forget to turn off "find my iphone" on that device.
