The BBC reports that while daytime temperatures in Stockholm have regularly dropped to -5C (23F), “it's still common to see children left outside by their parents for a sleep in the pram. Wander through the snowy city and you'll see buggies lined up outside coffee shops while parents sip on lattes inside.”
A poll in Norway asked parents how many let their babies sleep outdoors/outside a café and 84 percent say yes, they do.
My friend lives Norway, an hour from Oslo, and is one of the best mothers I have ever met and her job is to work with children ages one and two at a kindergarten there. She asks that her name not be mentioned so as not to upset her employer, but she told me just now, via Facebook chat, “Yes, babies sleep outdoors in Norway, privately and in day care and NO they are never ever unattended .”
She explained, “There are 14 babies in my section ages 1-2 and they all nap outside during the daytime for 1-2 hours they wear wool and then another layer on top of that and then they are in a sub zero sleeping bag. The fresh air is very healthy for them and they sleep better.”
“They sleep outside as long as it is not colder than minus 10 C colder than that some parents still request outdoors sleeping but our general rule is that unless really cold winds. There is ALWAYS an adult watching listening for breathing constantly checking that everything is ok. and when people do this privately, as everyone does, they put the stroller by a window so that they can check and it has never ever happened that a baby has been kidnapped here for this. In denmark they do the same. One danish woman was arrested in NY city for doing this outside a café.”
