Recently I purchased a new iPad 3. My old iPad (original) became more of a house / kitchen iPad, mostly used by my kids. I set up their e-mail addresses and put a bunch of apps on it that they would use. Because my icloud account was setup on it, the messages I send and receive are showing up on that iPad. I would rather that not happen and instead provide my kids with the ability to message us on their own using that iPad. When I went to set them up with their own iCloud I was informed that it is not permitted due to age. I realize I could make up a birthdate but I would rather not do that. Any idea why this limitation exists and how to work around it?
