After saving for quite a while Ella finally got to go to the toystore and get a marble run. We got the Haba one because all the blocks can be moved around quickly--lots of experiments. If you are local and haven't been to the new toystore at the old train station send me an email and I'll give you directions. They sell environmentally friendly wooden toys and cooperative games. I fear they won't survive.
She has been playing with the marble run nonstop and already wants more pieces. We brought in our big basket of wooden blocks to add to the building process so she can build castles and cities with a moving component. Even John has been propping up the "running" blocks and sliding marbles down them. I put some more components on the Froogle Wishlist for the holidays if you are a friend or relation with my littles on your shopping list. All in all, it is a toy I can recommend without reservations. I think that means that the grownups in our family like to play with it too.
