Girls are closing one gender gap we don’t want: diagnoses of Attention deficit hyperactivity disorder (ADHD). Between 2003 and 2011, parents reported an increase of ADHD diagnoses of 55% for girls, compared to 40% for boys, according to a 2015 study in the Journal of Clinical Psychiatry.

In 2010, Gustavo Rodríguez was a mergers and acquisitions banker for Merrill Lynch, living in London, where he had moved from New York. Then, he became a father.

Like many new parents, Rodríguez said the day his son was born was both the happiest and the scariest. “I realized how poorly equipped I was to provide this child with all the things he was going to need, especially in the first few years of his life,” he says.
