Abstract: A waist bag usable as a baby holder has a seat member disposed in a bag body and composed of a horizontal plate core and a vertical waist pad. An archshaped mouth has a central region formed in an upper and frontal middle portion of the bag body, and side regions extending from the central region towards lower and rear ends of the opposite sides of the bag body, so that the weight of a seated baby is distributed over the user's body, thus protecting him or her from fatigue during a continued usage of this bag. The waist bag is also improved in that the user can open the mouth wide enough for a shoulder strap or any article to be readily put in or taken out of the bag body.
