When we heard about YippieYo, it seemed like a logical next step for us. The YippieYo Crossbuggy is a pull vehicle for children that looks like a cross between a stroller seat and a cart. We received a YippieYo Crossbuggy to test, and I immediately fell in love with it. The times we use a stroller are purely for big outings, and the YippieYo Crossbuggy seemed perfect for that purpose.
