While I have never heard of this "Attachment Parenting" before today - I have to say that I raised my two boys based on them being a person (no matter how small they were) and with them always deserving the respect to be heard as respect is give & take even among a parent and child relationship...... and with what I have read on the link concerning AP I would have to say that it is a good way of parenting - a way that so many should be raising their kids.

P.S.
The only difference I can see in the way I parented my boys and with the way AP does it - is that I did use spanking as a form of discipline when I felt it was needed.
