re: Danger of wifi/router to a baby...

I would personally never put any devices capable of generating electromagnetic waves near toddlers. The effects of higher frequency EMF on our bodies are not very clearly understood, and some of these effects take a long time to manifest. I do not believe we have done enough longitudinal studies to understand their effects. And no, a 100MHz FM transmitter 10 miles away and a 2.4GHz transmitter 10 ft (even thought transmitting at 1mw) are not the same.

At our house, the WiFi transmitter is at the highest point in the house, is switched off at night, and the transmit power is set such that we optimally cover the whole house and not more. Similarly we do not place cellphones or cordless phones by the bed (they are away - also helps with the alarms as one has to walk up to switch them off and cannot just snooze), and try to use a Bluetooth headset instead of putting the phone directly on our ears (much much lesser power). If all these precautions are paying off, only time will tell. But I would rather be careful than sorry when I know our knowledge in this area is full of holes and is not well understood.
