Jenna's idea childproofs and tidies the medicine cabinet at the same time:
I've been looking for a way to secure medication in our house so that our two year-old can't get at it. I've seen a number of fancy medicine cabinets with locks but they seemed way too expensive. Instead, I've decided to buy a toolbox with a padlock. It will lock, be easy to store in any cupboard or closet, be easy to clean, and be easy to take with us (if necessary).
We could also have a couple of boxes in different parts of the house with medication and first aid supplies. If we do this, I'll be sure they are all accessible with the same key
