Interesting new research.  In the past, there was some evidence that middleborns were the most likely to have adjustment disorders (e.g., depression, anxiety) and suicidal thoughts — the good ol’ “middle born syndrome” — but new evidence suggests that youngest at greatest risk.  Here are some of the reasons given by the researchers:

Younger siblings are often bullied by their olders, with many known harmful effects.

Less parental attention and supervision and parents’ lower awareness of children’s psychological health.

Weaker attachment between later-born children and their parents because of less time with parents.

Also could be due to higher age of parents at children’s birth.  

Some interesting thoughts!
