Shifting heads

Do any of you have any advice for me?

I really like my job, and have a big project starting actually any second now, and have been very wrapped up in that for the past week. I'm having some problems separating from Work Moxie into Mom Moxie in the evenings. Last night it felt like it took almost until bedtime to have my head in the game momwise again. And I wake up with my work head on for the last few days, too.

Any tips for pushing the work aside? It's not that I don't want to be with the kids. It's just that I start trying to engage them in conversations about work. Which they don't so much care about, understandably...
