i find that mine prefer little woven balls (vine or willow) they can hold in their hands much more exciting than blocks of wood. same goes for apple twigs, they love them! they're gone pretty much instantly but they do enjoy it very very much! bamboo 'finger trap toy' is a favourite with mine, they also make different shaped things out of vine and willow - stars, little 'napkin rings' you can stuff with hay, that sort of stuff.
