My little one is only 9 months old but she's obsessed with the empty pawpaw ointment tub i washed out. She'd grab the full one and drop it on her face during change time so I saved an empty one for this purpose. After change time she'll roll it around the floor for a good 20 mins and then slug around after it. She also likes tea towels and will rub them against her face and pile her blocks into them like a sack.
