Exclusive - Totsy , a private sale site targeting moms of kids aged 0-7 (and moms-to-be), has raised $5 million in Series A funding from DFJ Gotham and Rho Ventures . The financing round follows the startup's recent "acquisition" of competitor bTrendie’s member base. Totsy is the umpteenth niche-specific (in this case, for everything from prenatal care products, baby gear, travel accessories to children's clothing and toys) to emerge, following in the footsteps of flash sales sites like pioneer Vente-Privée.com , Gilt Groupe and Rue La La .
