it is great! i don't take a single break (except lunch) so i am able to take the extra pump session, otherwise i would only pump four times a day at work. I am VERY blessed!
I think that, if you can stick, to the same schedule you have at home, at work, then you should do it. That way you are still meeting the demand. It is great that you are able to pump that often at work, so keep it up!
