Greetings and salutations; this is an interesting piece of writing you have done. I have found the tale entertaining thus far, though your ideas hop around a little bit. Some of it should be re-ordered and moved around a little, and some of the ideas could be worked in with one another.

For example, the third paragraphs talks about the Matron seeing if the Lady would allow Rosie to stay there, and the Lady consenting. You could then weave in the parts explaining who Rosie's grandmother was there.

Your descriptions are pretty good, though I've noticed you use a lot of commas. Don't be afraid to break off an idea and make it a couple of sentences. I do like the detail of Rosie's constant cough, it was a nice touch to the character.

All in all, you have a nice story going for you. A little bit of polish, and you can make it shine. I hope my opinions have been constructive and helpful, and that you continue to write.
