My parents and in-laws always let DS (17 mo) play with their cell phones and cordless phones and beepers. We don't let DS have the phone at home (since he called 911)--supervision is too much of a pain. But I figured these other folks could just do it their way.
But DH has brought up a couple of good points. One is about the broadcast frequencies of these things and some evidence that they can cause cell disruptions when used a lot. Nobody even seems to have asked if this is more of a risk with a developing brain and body. The other is that when he has these phones etc, DS is totally obsessed with staring at them and pushing the buttons, and doesn't interact with anyone or do anything else, even when there are all these great relatives around he could be playing with and learning from. Everybody just looks at him and says he's cute, instead of engaging him as a person.
Any opinions on this? I am fine with just not letting him have them, but not so thrilled with having to endure my family's disappointment and thinking-we're-alarmists.
