Personally I think that having something like that in MP would be cumbersome to use. I think your manual solution is best. Also, I have a 6 year old son. My Direct TV receiver has a 3 digit password implemented that allows me to restrict chanels on a user by user basis. On the 'family' account that the kids use I have porn channels and a some movie channels locked out. A month or so ago I walked in on my son manually cycling through all the numeric combinations to unlock the channels (the movie ones, hopefully not the porn ). He had figured out that if he started at 001 and went to 999 that eventually he would find the password. So your 2 week assessment for your daughter is probably more accurate than the 2 year one .
