Hm...now, I have breastfed succesfully enough (but yes opossibly cut shorter then I wished, to 10 motnh and 13 month ...with my younger 2...) and they used a dummy from the early days...but that is another matter...lucky I suppose...
However, I know the whole bf/co-sleeping (both of which I did) is based on teh "knowledge" that a Baby is less lilely to sleep to deeeply and so is the mum...
I wonder if, possibly, the main dummy users could be Formula/Bottlefeeding parents and that maybe the dummy helps a Baby go to sleep but sleep less deeply and rouse easier...obviously purely specualtion!
However, and this had never been answered and I can't quite work it out if or if not...but originally, after this advice was published, it was said, that it wasn't so much to push the dummy, but not to remove it, if your baby is using a dummy...I am sure that was the original implication.
Also, whilst I do not agree with devils approach here, can I just say, that it is not really that unreasonable to question the advice if it is sponsored by someone who makes a certain product that therefore is marketed that little bit more, and I am sure if this was about a Formula company doing this, there might have been more "support" in the outrage?
I might be wrong of course and missing the point....
