When Will was still a wee lad, one of our fabulous neighbors handed down a rather well-loved and rather big block set their boy had outgrown. By big I mean when one of those blocks lands on a toe, you know it! I was worried about such injuries at first but not many have occurred. What has occurred is many, many hours of creative play. Forts and towers and roads and castles ... learning about balance, cause and effect and a whole bunch of other skills along the way. I now love the big size of the blocks. I think they are easier (sturdier?) for building. I tried pricing a set like ours and they are not cheap. If you are handy with a saw and sander, make your own.
But really, this post is just an excuse to share a cute picture of Joseph. Look at that concentration!
