Provided herein is a baby wagon with improved ease of use configured such that the volume of the bulky body of the baby wagon is minimized in a wagon folding mode, whereby it is possible to easily put the baby wagon in the trunk of a small-sized car, such that frames are completely fixed in the wagon folding mode, whereby it is possible to prevent damage to the frames due to protrusion of the frames when the baby wagon shakes or is laid down, and such that brakes are mounted to the front and rear parts of the baby wagon in order to easily move or stop the baby wagon in opposite directions, whereby it is possible to improve the ease of use. The baby wagon includes a folding type body frame, a wagon wheel unit, a seat unit, and a canopy.
