Adkins - the big cinemas like Hoyts and Village usually have one a month, but our local smaller cinema has two a week (they are making a fortune off it) Some big cinemas also have a 'crying room' which is a glassed room at the back of the normal cinema so you can go into any session and if bub is noisy just step into the crying room and watch the movie from in there. Olivia and I went a lot last Summer when it was really hot and we didn't have aircon.
