My kids are now entering college, but when my first was born, I remember getting a subscription to a really great toy service. We received a new toy in the mail every month along with an explanation of why that toy is valuable to your child's development: for example, I remember a tube full of water with a bright red marble in it that was supposed to improve the ability to track objects with the eye. The toys increased in complexity each month.

Does anyone know who offers this service? A friend of mine just had a baby and I think this would be a perfect gift.

Wow, I've never heard of that, but it sounds great!
