But, but......FT, my post with the quote came immediately after yours, but that does not mean it was a response to yours, or that I was quoting you....this is how a talkboard works, sometimes 'cross-posting' happens. Contiguous posts are not necessarily in conversation with each other (this is why there is a convention to use the poster's name at the start of a post, if it is directed at one person in particular).
You certainly sounded annoyed, with your comment about this folder having a bad rep! But maybe I got that wrong, sorry.
I don't know why it is odd to ask people for evidence - my concern was that when someone said (not you) that most babies are likely to be in pain unless they are winded, it adds to the worries and nervousness of new mothers...unnecessarily. If this is true, then I'd like to see evidence (there is none, AFAIK). I think mothers have enough worries without adding to them.
(Yes, I have had babies, since you ask - I have three children).
