Tummy time play: extending the tummy-time prop into a single layer pillow encourages the littlest ones to push up and discover attached toys; the toy arch can be added so toys dangle temptingly within reach. Seated play: stacking the tummy-time prop transforms it into a secure, hugging "C" shaped positioner for early sitting playtime; adding the toy arch and repositionable toys creates a mini gym for entertaining prop-up play.
