Babies with a cordless baby monitor in their bedroom appear to cry more, be more irritable and sleep worse than babies monitored by a wired monitor or babies without a baby monitor. So reports an informal survey by Powerwatch UK.

Parents also noted that their baby’s sleep and mood improved when a cordless monitor was replaced by a wired monitor or electronic monitoring was abandoned altogether.

The finding is worrying, but no surprise. A cordless (DECT) monitor in a baby’s bedroom exposes them to as much pulsing microwave radiation as someone using a cordless telephone and more radiation than living close to a mobile phone base station.
