Sendak's Moon

I leanred (although I'm not sure how reliable it is) that Sendak was "sickly" as a child. The website that I was researched off of said that the moon that is in most of his pictures in most of his books represents his mother (in reality) always there looking out for him when he was a young boy: "The moon is his mother peaking out the window at him when he was a child to be sure that he was alright!" The website I found this at was: http://falcon.jmu.edu/~ramseyil/sendak.htm. That site has referenced this information to a Berkeley website, so I'm pretty sure it's legitimate. But I just thought this was interesting and felt the need to share. This is an interest additional piece of information to the fact that the moon gets bigger and bigger as the night goes on and the boy character becomes "more wild."
