I’m using a program called “Zoodles” with my middle child who is six. She launches the program and has access to only content I’ve made open to her, which is some games, some videos, things like that. You have complete control over everything and get a report each day or at the end of the week of what the child did in the program. Alot of it is nickjr type stuff. One neat thing is you can record yourself reading books on Zoodle and they can play you reading them the story as much as they wish. You can set up accounts for more than one kid and have different things opened up for each kid. The program also takes up the whole screen and requires a password to get out of it, which is great because my daughter can’t accidentally mess up any settings on the computer.
disclaimer: of course there are unkosher things available in the name of “children’s content”, I’m not ignorant of this. Our computer is in the middle of a public space, I always know what my family is doing online both through programs like this but also through our whole house internet filters (we have two separate ways of recording EVERYTHING that happens online – covenanteyes and openDNS). If you feel the internet is without question an uzi in the hands of anyone (child or not), you probably shouldn’t be using it yourself.
