We have one of those wooden beads on metal wires on a frame things, and dd loves it! She also has a rocking horse that's all wood and fabric, and totally appropriate for a seven-month-old: it's got a corduroy chair-like seat behind the horse's head and little wooden beads on dowels on either side of the head.
She also enjoys spoons, metal pots and pans (the little ones), her board books, wooden blocks, and stuffed animals. And any of my necklaces she gets her hands on.
