I used these drawer and cabinet locks way back when my kids were babies, and now they are useful to have now that I have a granchild that visits often.
Safety 1st makes a wide variety of different style locks. It's easy to find just the right kind for the particular cabinet or door we have. They are a very inexpensive way to have piece of mind that your home is safe from poisoning accidents.
Some locks need no installation, while others are attached with just a couple of screws and easily removed when they are no longer needed.
Although the locks are easy for adults to unlatch, they have shown to be fool proof in our home by keeping the children from getting into things they shouldn't.
