Well, that was interesting. I think I generally liked most of it. I enjoyed the unreliable narrator aspect of it, that he claims that there is no evidence for him being a poor guardian, but then on his first opportunity he shows himself to be terrible at it. Especially the moment where the baby disappears into the drywall and he is not even slightly concerned because he figures she'll come out when she's bored, and so he grabs a beer.
The ending didn't really seem to fit with the rest of the story for me, which I guess was the point to be a stark contrast to the odd comedy of what came before to the realization of a baby corpse. To me I guess it was too much of a contrast and I felt that it just didn't really fit the rest of it at all, and so the rest of it is what sticks in my head.
I didn't mind the stereotypes. Stereotypes can be offensive, but at least sometimes they can be based on people who actually have those characteristics, in which case I don't see a problem with using them. I have a co-worker who, when asked to watch his own children while his wife has the rare evening away from the house, refers to this as "babysitting". I wouldn't be terribly surprised if this story had actually happened with him. Likewise I know women who have said that they will have a natural childbirth but then ended up going back on that in the moment--that's just a very real possibility when one makes an ideological decision without really knowing what the consequences will be for you, in the actual moment you have to make the choice between your ideology and your potentially torturous present moment.
