The very earliest memories I have are that of being an infant and really liking the mobile over my crib. It was the kind of godawful workmanship that isn't allowed these days for infant toys. It was made of thin rods of metal, suspending puffy vinyl birds, printed on both sides and heat crimped around the edges, stuffed with who knows what to make a pillowy item. There were blue jaybirds, red cardinals and yellow and black oriole looking birds. I loved it. I have asked my mother, and she was blown away but did confirm that is exactly what hung over my crib and exactly how it was fabricated. Moral: don't ever underestimate what your kid is taking in. You might be surprised.
