I use mine far less often nowadays, but I certainly wouldn't be without it. However I wouldn't prevent a guest's one off use. When dd and very little Gdcs are staying I will often wash and TD their things to save her having yet more washing when she gets home.
As for your young guest, OP, since there's a TD there, presumably he thought it was there to be used.
