I have read many recommendations about not keeping newborns upright due to skeletal development to support the head.
However, I also have (and use) a papoose style carrier in the ErgoBaby (with infant insert).
My 3 week old enjoys being carried in this way, and will often sleep very well in the carrier (though we don't let her sleep upright longer than necessary).
Should I be concerned about her skeletal or brain development from being carried upright like this?
