My kids have "inherited a play kitchen" from their aunt. She bought
new play food since the old stuff was mostly missing or mutilated. =-)

Some of the new play food are boxes that resembles the packaging
found in the grocery store. Since they are empty, it only took about
5 minutes for them to be squished and some even ripped by my one-year old.

To fix them and make them more durable, I stuffed them with plastic
bags and taped them shut with clear packaging tape.

To augment what they have, I bought or gave them the following and
put them in the playroom.
- Single-serve cereal boxes.
- Empty water bottles.
- Old Tupperware used for my husband's lunch box.
- Wicker baskets.
- Plastic fruit donated by the grandparents.
- tablecloth and napkins (also used for bathing animals and babies)

What ideas do you have?
