An adjustable infant holder apparatus includes a support structure that has a base support and a head support situated at opposing longitudinal ends and mutually coupled by a longitudinal stabilizer. A seat is adjustable between an inclined lying position and an upright sitting position. The seat has a base end that is suspended from the base support and a head end that is suspended from the head support. Optionally, at least one of the base and head ends is suspended by at least one cable that permits the seat to swing back and forth laterally. Embodiments include a linear actuator that can force the swinging motion.
