If we judged toys purely on how long kids played with them, Christmas would be just a pile of ipads. I don't have kids, but do watch in amazement as young parents buy toys less for the child and more to reinforce their theories of scientific parenting. The kid's brain will develop with or without the "correct" toys. Maybe confinement to such "play areas" is the issue. I don't confine my puppy to pay in a particular zone of approval. Why a child? My play area as a kid was 'the house' or wherever else I found myself.
