Wait Till the Moon Is Full - Margaret Wise Brown - Bog

There was once a little raccoon who wanted to go out in the night -- to know an owl, to see if the moon is a rabbit, and to find out how dark is the dark. But his mother said, "Wait. Wait till the moon is full." So the little raccoon waited and wondered, while the moon got bigger and bigger and bigger. Until at last, on a very special evening, the moon was full.
