OK, so I love the idea of these and will be using them. Amongst my many other confusions with them (pregnancy seems to make me overthink) is this...
Can newborns use them?
The grobag website and most retailers have a 0-3mths or 0-6mths catagory, so I'd assume so, but the general feel from users is they didn't use them for the first 4-12wks???
What have people done, and if not used before a certian time, why?
