Q: My daughter has an iPod touch using my apple ID, I just purchased an iPhone with the same ID. Is there a way to keep my stuff seperate from her ipod but still share the iTunes account?

If you have iOS 8 on all devices then:

If under 13 years create a new ID for her by:

Family Sharing and Apple IDs for kids - Apple Support

The use family sharing to share apps

http://www.apple.com/ios/ios8/family-sharing/

Family purchases and payments - Apple Support

If underage and not i)S on all devices then you have to create an ID for here under your name and supervise it use:

Create a NEW account using these instructions so yo do not have to use a credit card.

Make sure you follow the instructions. Many do not and if you do not you will not get the None option. You must use an email address that you have not used with Apple before. Make sure you specify a birthdate that results in being at least 13 years old

  Creating an iTunes Store, App Store, iBookstore, and Mac App Store account without a credit card

Use the new ID on her iPod but only for:

Settings>Messages>Send and Receive

Settings>FaceTime

Settings>GameCenter

and Settings>iCloud if you want her to have separate Contacts Calendar and some other things.   

Continue to use the same/common Apple ID for Settings>iTunes and App stores so you can share purchases.
