I thought I had recommended Magnatiles on my blog somewhere previously, but I can't find it, so I am assuming that I did not. So here is my recommendation. BEST TOY EVER. Seriously. Quite expensive but truly worth every penny. The boys continue to grow and build bigger and better things. The toys are incredibly durable -- like incredibly. And Abigail is now into them. I cannot recommend this toy enough folks. Buy it!
