Are women overrepresented in the field of child development studies? I have the impression that many female scientists, especially after they gave birth to a child, start to develop a research interest in the learning, growing, and developmental behaviors of babies. I got this impression because over time I heard about a couple of female university professors and industry scientists doing research about babies. I personally know 0 male scientist whose research interest is in this area. 

I'm wondering whether this trend I see around me is real, and thus wondering: are women more represented in the subfield of child development (or developmental psychology) than in the broader field of psychology?

I'm concerned, and intuitively don't like this (possibly imagined) "trend". I think it may encourage some people to think that female scientists just pick up certain research topics and don't want to touch others. I also see this "trend" as a destruction of many years of effort encouraging women in the "hard-core" science and technology.
Males have historically outnumbered their female counterparts in the field of psychology, but this has changed in recent years. According to the American Psychological Association


  Psychology, once a man's profession, now attracts mostly women. Data from the 1986 APA report, "The Changing Face of American Psychology," and the National Science Foundation show that the percentage of psychology PhDs awarded to men has fallen from nearly 70 percent in 1975 to less than 30 percent in 2008. (The data do not include PsyD degrees.)


Not only are females over-represented in psychology as a whole, they appear to be even more over-represented in the sub-fields of developmental and child psychology. This article from the APA states 


  In developmental and child psychology...female PhD recipients outnumber men by more than five to one.
