Transfer content from one Apple ID to another?
You cannot. It's not possible to share content from one Apple ID to another. Apple actually recommends everyone have their own Apple ID.

You can load the content on your daughter's device and she can access them all normally. You can then log her into her own Apple ID, where she can begin to make her purchases on her own account. The only downside is she will have to know your Apple ID's password as iOS will ask for it on rare occasions (when restoring the device for example). It's possible to store content from multiple Apple accounts on a single device, the user will just need to enter the password should the OS ever require it. That is the only feasible solution in your case (other than starting over). This will at least circumvent having to re-purchase any content.

This has always been a sore spot for Apple customers as they have historically been very firm in never being able to even close an Apple ID, let alone share content between them.
