Do you have a recommendation for a low-EMF baby monitor?
The safest baby monitor is to never use one. Wired solutions are next - like a camera using a wired Ethernet cable instead of a wireless connection. This is a great article on the topic https://www.emfanalysis.com/safe-baby-monitor/
There a few "low-EMF" baby monitors on the market, like this one https://bebcare.com/en-ca/pages/bebcare-hear-audio-baby-monitor or the https://www.amazon.co.uk/NUK-Babyphone-Eco-Control-Video/dp/B007CK1ESS (Europe only if I recall correctly). But, none of these emit levels of wireless radiation that can be considered "safe".
Placing any source of wireless (even the low-EMF baby monitors) as far away from the child as possible is optimal and the safest way to use it. Monitors I've tested pick up sounds just fine even at 12-15 ft. from the child.
