Once a baby can sit upright without support, they’re developmentally ready to sit in a high chair. A high chair, raised at a fair distance from the ground is used to feed the baby and young toddlers. The distance enables the adult to spoon-feed the baby from a standing position comfortably. Hook-On high chairs, which are also popularly known as clip-on high chairs, are generally safe with their three-point harness.
