Small nesting cups. My 10 month old just discovered these and probably would have sooner but they've been with the bath toys.
I got ds a ball drop and soft ring stacker, I think it's Tiny Love. They have them at Target. He's not stacking them much but loves to drop the balls in and see them roll out. It can take batteries for added "entertainment music" which I've chosen not to do.
Small matchbox size cars. Ds 2 never plays with the larger wood rolling cars which I thought were so nice, but alway goes for ds 1 matchbox cars. He also likes ds 1's wooden trains.
A big soft cloth ball.
I saw a great little wood ball toy, it was a link of 7-8 colored wood balls, at Barnes and Noble, I think it was Manhattan. Ds didn't want to let it go when I let him hold it the other day.
