Of the menagerie of talking, beeping and blinking toys, perhaps the most popular playthings in our home are the ones that don’t make a sound at all. No motion sensors, no batteries, no noise: the kid loves these toys as much as us. Silence–and simplicity–is a beautiful thing. Haba, Melissa and Doug and Plan Toys are some popular picks, but Nuchi is a newer line that I have my eye on, particularly the simple and classic train sets, like this Oval Train Set w/Crossing Barrier.
