I am currently studying for a Masters and in some of my recent
assignments I have looked very thoroughly for references to show
links between breastfeeding and later emotional and mental well-being
including social adjustment. The title of my assignment was a
literature review of Infant feeding and its associations with
emotional well-being, in mother and child.
The fact is, there is hardly any robust research out there at all.
There are many, many papers and studies which purport to find a link,
but the studies are flawed, mainly because
* the definition of 'breastfeeding' is not clear - 'any'
breastfeeding may be recorded as 'breastfeeding' ; there is no
attempt to differentiate between exclusive and partial; some papers
make a distinction between 'breastfeeding for x months' and
'breastfeeding for y months' but not all
* the controlling for confounding factors is very variable - much
less well done than the research into physical health outcomes
Julie mentions this study:

Now, this is an interesting study with a big sample (almost 9000
children), and it was one of the papers I took apart for my
assignment. It purports to show that breastfed children cope better
with psychosocial stress, operationalised as their reaction to later
parental divorce/separation. This reaction is scored by their
teachers and their parents. The breastfed children appeared less
anxious (at age 5 and 10) than the non-breastfed children - and many
of the non-feeding related reasons why this might be so are
controlled for. The length of time the children had been breastfed is
defined and there seems to be a 'dose response' effect.
My superviser did not like this study much, but he is a sociologist
whose special area of research interest is divorce, so he thought the
divorce part of the research was pretty crude. I thought the
breastfeeding part of the research was pretty crude ( no
differentiation of full or partial bf, for example).
But from my reading, it's about the best study there is in this
field, academically speaking, despite its flaws.
