Well that would be what she is looking for, but she does not want to jail break the phones. Are there any apps that "run silently" this without jailbreaking?
if every kid has a Different apple ID then she has to use multiple browsers for each kid
lets say that she has 4 kids
first kid: www.icloud.com from google chrome
2nd kid: ================= internet explorer :S
3rd kid : ================= find my iPhone app on her iPhone etc...

The best app to track any apple device is, by far, find my iPhone. As long as the kids have their location services on, then you can track any of their apple devices by logging onto find my iPhone online. If he kids have multiple apple id's then you can keep multiple windows open, with one window assigned to one child.
