Given that many, or all, aspies have been so since birth I think any research on newborns and infants would be interesting.  My son was born 4 weeks early (labour was induced because he had stopped growing), refused to breast feed and was extremely difficult to bottle feed.  Moving him onto solids was also a struggle and he continues to be the pickiest eater.  The emphasis on breast feeding rather than bottle feeding was unhelpful to say the least, and I wonder now if the sensory aspects of AS were at least a contributory factor in any or all of these early difficulties.  Also worth mentionning here is that at less than a month old and in an incubator he was extremely active and banged his head as soon as his neck was strong enough.

Research on this would be incredibly helpful for mothers like me who really struggled with feeding a child, which is so fundamental to a maternal relationship.

I don't know if there's any research on a possible link between low-birth weight babies and AS.  I think I read somewhere that underweight children are over-represented among aspies as opposed to NTs.
