Wooden puzzles

If your house have small children, it is good for you to invest in buying wooden puzzles. I bought a set for my girls and they can play it more than an hour. They love to build anything using the puzzles, all sorts of funny and creative ever built by them. Once they started playing it, I can relax a bit. I can do my own things while supervise them playing the puzzles. My puzzles are in big block, so I no need to worry they will swallow it. LOL
