So after asking your opinions thought I should update you on how it went. It went much better than I expected! However, not sure if she liked the movie or popcorn more . Luckily theater wAsnt busy at all and we were on an aisle so I wasn't super concerned with her talking or moving. She didn't want to sit in seat by herself for long and was either standing or sitting on me the whole time. It helped she was with her friends and saw them demonstrating good theater behavior. I will take her back but not in any hurry to .
Ps note to self and other parents. The light up shoes were not the best choice
