Shake up baby’s routine™ with Waddle™ Rattle Socks™. Each pair of comfy socks, which fit baby’s feet from birth to 12 months, has a rattle attachment on the front that is designed to aid in developing sensory skills through sound and touch. Every time baby kicks, the socks will make a rattling sound. The bottoms of the socks have the Waddle™ logo as a non-slip gripper. And parents won’t have to worry about these socks falling off because these soft and stretchable socks stay on baby’s little feet. The Rattle Socks™ come in a variety of designs for boys and girls, including socks with fluffy pom-poms and trucks as the rattle attachment. Plus there are gender-neutral designs and holiday designs with reindeer and Christmas tree rattle attachments. You get two pairs of socks in one package, and each package is sold separately.
