Baby sensory play for a 6 to 9 month old baby. Wrap cling wrap around a canvas and have the baby smoosh away with their hands and feet. So much fun, but I'd do it without the Cling wrap! Edible paint and babies are washable!
An activity board I just made for my tots. Went to the hardware store for knobs, locks, lights, etc. and screwed them into an old kitchen cabinet door. Everything they ever wanted to play with (but was off limits), nailed to a board.
