I'm interested in the recent discussion about thumbsucking.  It reminds me
of an area about which I would like to see a study done. All three of my
children tried at some point to suck their thumbs (in the first three
months).  I took it as a sign that they weren't getting their sucking needs
met so nursed them more until they didn't suck their thumbs.  None of them
ever sucked their thumbs after that and don't have any other oral fixations
that I can see yet.  Has it been other people's experience that thumb
sucking is an indication that baby has not been breastfed enough?
