First Aid Kit

I have a first aid kit at home. It was 2-3 years ago when I bought it.
Recently Juliane had a nasty fall in school. It was only because of her fall and I tried to dress her wound at home that I realised some of the medical supplies in the kit have expired in 2012/ 2013. Oops! :S
It is good to have a first aid kit in the home, however, it is also good to check it periodically in order to replenish supplies as well as to throw out the expired ones. :)
