App download on new phone???

[CRK17]

I just updated my old iPhone to the iPhone 5. Prior to activating it I created a new iTunes account since previously we had one account for the family which I didn't want to use anymore. When I connected the phone to the computer for the first time and opened my new iTunes account it loaded all my previous apps on to the phone. I should note that when I was setting up the phone I put in my new iTunes account ID and password. This is nice except I don't want this to happen when I activate my wife's new phone. Like me she previously synced to the family's iTune account which includes many of the kids' apps. We also created a new iTunes account for her. How do I make sure the apps in the old iTunes account aren't automatically loaded to her new phone and iTunes account?
