The bottom line is that you can create a new ID, still use her ID - judiciously - but you really want to avoid downloading past purchases with her ID. This explains it in a little more detail. This is one way that Apple hopes to cut down on pirating of apps - friends using other friends IDs in order to download apps without patting for them. When you download a past purchase with a different ID - you associate that device with the different ID for 90 days. So you can keep using the apps that were bought with her ID, you can also update those apps using her ID (you have to sign into her account in Settings>Store) but you can't download past purchases without messing things up with your new ID.

So as long as you do NOT download any past purchases with her ID - you will not lock yourself out of the new ID. If you create a new ID and then you sign into her ID in order to download a previous purchase- you will lock yourself out of the new ID for 90 days and there is nothing that you can do about it. What you do want to avoid is having to download any of those purchased apps again on any other devices - if you create a new Apple ID. You can continue to use your daughter's Apple ID in order to continue to use the apps that you purchased with her ID and you will need to use her ID and password any time that you want to update those apps. You can't transfer purchases from one account to another account. I hope this isn't too wordy but I want to be as clear and explicit as I can for you.
