musikit writes "My wife and I have recently found out she is pregnant with our first child. She thinks that WIFI and cell signals pose a big risk to the child, or maybe she just wants to reduce any impact while in the womb. Today in Ikebukuro Tokyo she bought "RF blocking maternity belt" but on testing it, it did not block out our cell phones. I looked (briefly) into it and discovered http://www.bellyarmor.com/ that apparently has this type of wear. Can anyone recommend this or other brands? is it effective? is she off her rocker? Most appreciate the help."
