I just give them toilet paper rolls (stuffed with hay sometimes) and they LOVE them. I also stuffed an old sock with tissue paper, then I put another sock over it so the ankle hole was covered (or you can tie it off). For floor time, I give them 12 pack soda can boxes with the ends torn off, they love running through them. I have also given them a butter dish I'd washed, they loved flipping it around.
