The front of pouch extends downwardly and is brought up between the child's legs forming a crotch, then extends upwardly forming the bib section of the sack where two releasably attached straps pass over the child's shoulders to their anchoring points in the front of the pouch. A crotch strap then extends forwardly between the child's legs, loops around the chair seat, and upwardly to a quick release device at the lower extremity of the back pouch section securing the pouch to the chair.
