Introducing the Tiny Love TinySmarts Adorable Jittery Clip-Toy - Heidi Hedgehog ..
0-2 months - Hold in your hand at 10-12 inches away from baby's face, and allow baby to observe it.
2-4 months - Baby reaches out with her hand - at first, randomly, and gradually, with purpose - and bats at the toy, causing it to swing and make pleasing sounds. This effect is captivating and encourages her to try again.
4 months + As baby’s grasp reflex disappears, control of her hands improves, allowing her to reach out confidently to bat the toy or grasp it for further exploration.
