About Kingpin's advice, you can search for parents influencers. People who post about life with kids, and so on. About FB ads, in America not only women buy clothes and stuff for kids, men also buy stuff (check out this page on facebook: Fatherly and read their description). What you can do is shorten your age range to 28-50 (educated higher income parents are most likely to be older than 25) and target men and women who have children. You can even make some test ads with the same age range and be creative, let's say, target people who are interested in Toys R Us, Barbie, Max Steel, depending on the product you are promoting.
