ravenia - have namechanged since I last posted! I have literally done nothing else apart from sleep and write and throw the occasional meal at my son since Monday, despite wobbles with less childcare than I thought we had and a small loud person trying to sit on my lap whenever possible, but DH stepped up manfully.
As for how it's going, I'm now too close to it to have the faintest idea, tbh. When I sat down on Monday, I hadn't touched it since mid-June, where I had to break off shortly before the ending (well, say nine-tenths of the way though) but I decided I needed to go back to the beginning and rewrite heavily as I went through, in order to put me in the right place to write the ending. Whereupon I've discovered lots of things that need work, and that's what I've been doing.
My big issues as always, are structural. It's a first person narrator who is remembering episodes from her own past as well as involved in drama in the present, until the two come together when a significant person from her past shows up - but I'm worried about pace and how much time I'm devoting to the past, compared to the present, and whether the reader always has a firm grasp on where exactly we are in time when there's a transition.
Basically, I'm an idiot, and am retrospectively doing things that any normal novelist would have done at the initial planning/synopsis stage. 
To the people struggling to keep things in their heads (of whom I am one), Emma Darwin has a wonderful recent blogpost about the usefulness of synopsis writing:
