Let baby sit on your lap or if it is still very little lay across your thighs. Bounce your legs up and down softly and allow your baby to feel the motion. Make sure he is enjoying himself. After 15-30 seconds stop bouncing, you may even say cheerfully, “and stop.” After a few seconds say “go” and begin softly bouncing again.
If your infant enjoys this, feel free to vary the baby’s position. Move a newborn to face the other direction or move your infant from facing away from you to facing toward you.
