The Sassy Growin" Up Golfin Set is designed to grow with baby from 3 months with simple tactile, visual and hearing features to stimulate the senses of fine and gross motor manipulation, and cause & effect play by filling the simple bag up and dumping it out. Then as baby gets older he can manipulate the golf clubs and pretend just like Mommy and Daddy! Babies love this activity and you can feel assured that baby is learning as he plays!
