To all the Nordic mommas...

I've been seeing this article circulating my newsfeed about why is common for nordic parents to out their babies to sleep outside in subzero temperatures.

I'm just wondering if this is real and is anything you've ever seen. I'm curious about this. I'm from the US, so our recommendations on sleep are much different than the rest of the world. I'm curious as to whether or not this would even be legal here.

I have no judgment here. I think its very interesting and I'm just genuinely curious.
