Umm... no, my son does not, will not, have that sort of access at anytime.
Are parental controls in place on all of the electronics? That's the first place to start. Second, devices should be out in the common areas.
It might be good to find some articles which support your opinion instead of just stating it. Find some information which explains to him the serious dangers of unguided, unlimited internet access. Sure, she may not be interested in chatrooms or social media at eight, but what about 12? or 15? Those later ages are when these concerns come more to the fore, and what will he plan on doing then, backpedalling? It's better to set the precedent that all electronics have parental controls and stay out in the open if they have internet access. It might also be good to put some controls on which allow him to track her access... if he disagrees, remind him that if she's not doing anything inappropriate, there should be nothing to worry about. It's just good common sense to monitor a child's internet access. Would you allow them to go downtown alone? It's almost the same thing, right--unlimited, unsupervised access to the 'net. Just my two cents.
