Looking for opinions on part of my first novel

I mentioned in the post I wrote about the movie Brave that I might need to amend or rewrite part of my first novel to accommodate it.  I can't decide because I kind of like it the way it is, but it could seem like an obvious omission since the novel has yet to be published.  Or maybe I should leave it as a reflection on when it was written, rather than update it?

I could use some opinions if anyone is willing to take a few minutes and read an excerpt.

The name of my novel is The Real Mom, although I'm considering changing the title to Pink Ponies.  It's about Maddie, an artist who is married and is the stay at home mom of two young girls.  This excerpt is from the middle of chapter four after she's found out she's pregnant again, and she's taking care of her girls while making dinner and waiting for her husband to come home.  (I look forward to the day when anyone who is interested can read the whole thing.  Which could be soon as I am about at my limit with rejections from agents and may just self-publish and be done with it.  If anyone has advice on any of that I'd love to hear it too!)
