I posted this response over at @MomSpark Forum in answer to the question in the title of this post. Add your first experience in a movie theater over @MomSpark Forum not on this post.
We had a few AWFUL “first time at the movies” experiences.
I took my then-3-year-old to see Tarzan. In the first 5 minutes Tarzan’s mom and dad are mauled and killed by a tiger off screen. Lots of roaring. 3 yo kept saying “Where Tarzan’s Mom and Dad?”
I took the same child to see Elmo in Grouchland at the movie theater. Within 5 minutes Elmo’s blanket fell down Oscar the Grouch’s trash can or maybe it was the sewer. In any event 3 yo cried so hard, one of us had to go to the car for her blankie.
Other odd movies we took kids to. Lilo & Stitch — 4 yo was scared of Stitch when he froths at the mouth.
I took my 1-year-old to see Because of Winn Dixie at a Mommy-Me showing. All the other moms brought babies who slept through the movie. My 1-year-old climbed up and down the steps. Wouldn’t eat any of the snacks. Was loud. He watched about 5 minutes of the movie.
