We have brilliant childlocks on our kitchen cupboards - they're magnetic and you have a magnetic 'key' that you line up with the lock (which is inside the cupboard) and it clicks open!! They're really cool - just have to make sure that you have a spare key for when one of your children (or even DH) locks the key inside the cupboard The best thing I've found about them is that you can flick the lock open if you want the cupboards to stay unlocked and flick it back when you want it locked again - great for when you're putting dishes away, and great for grandparents' houses that don't need to be childproof all the time.
