my Mom who grew up in Canada back in the 1920's would leave me outside in the baby buggy during the winter,lots of blankets of course.she felt you had to expose kids to the cold and fresh air!
maybe thats why i like to campout so much??
Scandinavian moms also put their babies outside like this for naps in the winter...same idea I think. Apparently the babies sleep better outside in the fresh air, and my Finnish friend says it is supposed to help reduce the risk of asthma/allergies.
