It’s always nice to hear movie stars sign on to sound views of bourgeois life — like taking care of their own children. But before we get too misty about Julia Roberts’ stay at home mom reverie, consider the reality: She is 40 years old with 2 year old twins and a 9 month old. The inescapable age/energy equation just makes it a whole lot easier to forego being superwoman at 40, than, say, at 27. And, of course, there is the constant hope that (we) older parents can compensate for that lack of raw energy with all those years of wisdom. Good for her if she’s there.
