I chose to review your item today as part of my review challenge at the "Invalid Item" .
I gave it four stars, because, although it didn't affect me emotionally, I was impressed with the message it conveyed.

Plot:
A privileged woman is approached by a strange mother and asked to take care of a baby. The woman, understandably, refuses such a hearty responsibility, despite it being clear that the child would be better off with her. The woman continues with her life. It is not long, however, before the event comes back to haunt her. You don't spoon feed your audience, so there are a few ways this could be read. The simpler interpretation, the one I initially held, is that the mother was a demon in disguise and punishing the woman for refusing to help. Upon further reflection, I decided that the mother and child were completely normal when we first met them, and it was the woman's heartless actions that transformed them into such monsters. As such, she brought her gruesome fate upon herself.

Symbolism:
The story is a metaphor for... well, it's a metaphor for something (I'm not to good at that sort of thing). Maybe, "what goes around comes around," for lack of a more eloquent phrase? It's saying that we ought to be careful of being selfish, as our actions can have serious and unpredictable consequences that may, in the end, make things worse for us.

Characters:
The main character was a realistic, average woman. Her actions were believable and made her easy to relate to. I didn't like her much; I was kind of glad she died.

The difference between the mother we saw at the bathroom and the monster in the cabin threw me at first, and it was this that prompted me to conclude that perhaps the timescale was not meant to be taken literally.

Max was an unimportant character, like an extra. His purpose is to make the woman's life appear more average, and to give her something to be happy about. Curiously, he is the only named character.

Descriptions:
The descriptions were the highlight of the piece. Phrases such as "a naked light hung from the yellow ceiling casting dim shadows about the room" really show off your proficiency as a writer.

Emotions:
I didn't really feel afraid as I read this piece. I think the word limit was a significant factor here. If the plot and the terror were given more time to develop I might have felt more while reading.

Thank you for sharing this thought-provoking and beautifully grotesque short story, and congratulations on the slice win!
If my interpretation of what you were saying was completely wrong, don't worry. Your writing probably conveys your intent perfectly adequately. My English teacher has told me before: "no interpretation is wrong, but this...this is really weird." So yeah, I have been known to pull random stuff from nowhere!
