According to developmental child psychologists, gender identity is established sometime between the ages of 1-2; at 18 months, most babies already have a notion of it, and where they fit in. The prevailing orthodoxy used to be to emphasize the importance of nurture over nature in gender identity development - the idea that one is mainly conditioned into one's gender (pink for girls, blue for boys, etc.) I could quote the relevant academic references for this, but you'll have to take my word for it, as this is a blog, not an academic treatise.
