It is really nice to be able to get this one too. The older people helping are the neighbor's parents (they supplied the logs) and they bought the playhouse for their daughter - my wife's best friend. We took them through our house and they hadn't been in it since the 60s, when the mother's parents rented our garage for their car. Locals :)
I think Smallsteps will have fun in there.
I think kids like tents and things because it gives them their own space - somewhere that they feel is their own little fantasy world.
