I really wonder about the person who thought of designing this product. It is extremely dangerous. The baby, when it is a newborn, cries constantly because it is hard and smooth, and of course, it moves back and forth on it with the water and gets scared. As soon as it grew a little and started to move, it was the cause of hitting because it completely went out. If the parent is an octopus or if two parents are bathing a baby at the same time, then yes, it has a nice inclination for the correct body posture. Otherwise, we naturally got these soft bath pillows and literally saved ourselves. It should be noted that we used it normally and correctly inside the baby bath with the high base.
