My feeling to this short story is a introduction to life at a hospital. an example of this is when it says "the blinking of numbers as loads of strangers were shuffled from wing to wing. This quote alone gives me a pretty good idea that in this hospital is very hectic and stressful. 

the second paragraph tells me she is probably had suffered a miscarriage . where it says " she had to go into labor knowing she would give birth to the dead.

for the rest of the story, the mother is telling her unborn deceased baby that it is not your fault. Your birth was never met to be and unfortunate i wont be able to see you grow up.

for the last paragraph i get the sense she is talking to her past self from one year ago. also asking her future self what have you been doing since it happened. it has a Charles Dickens. A Christmas Carol 

feeling to it .
