The Passage of Time
13 years ago (approximately), we took an infant DJ to the midnight showing of Harry Potter and the Sorcerer's Stone. She nursed occasionally, slept through the whole thing, and likely no one else in the theater knew she was there. It worked wonderfully. (In part, this was because we were young and were more resilient about late nights than we are now, but leaving that aside....)
A year later, we tried to do the same thing with Harry Potter and the Chamber of Secrets. This was rather less of a success, as she woke up during the climactic scene, became scared by the basilisk, and I had to remove her to the lobby for a time so she could calm down, nurse, and go back to sleep. We did not take her to the movies again, that I recall, until she was old enough to enjoy the movie herself.
Now, she's watching that exact climactic scene with obvious enjoyment.
Time is so weird.
