There are some that can help you monitor your children's activities online. The new iPhone coming out in the fall will have a built in ability to control how much time your kids spend using apps. Yeah!!
The apple store probably won't be much help. However as a tip if you login to imessage with their apple ID on your computer you will see anything that goes through their phone. That is not foolproof though and there are better ways to 'keep your kid safe'. So jump online and get surfing. :-)
