Start with one reusable swap

You do not need to overhaul the kitchen to make a useful change. Pick one routine that happens often, make the reusable option easy to reach, and notice what gets in the way.

Try the lunchbox routine

For the next five school or work days, put a reusable bottle and snack container beside the bag that leaves the house. At the end of the week, talk about which single-use item was easiest to skip and which one still felt necessary.

Keep it kind and specific

The point is not a perfect plastic-free week. It is to find a repeatable swap that fits your family. If a reusable option is inconvenient, adjust the setup instead of calling the week a failure.
