I found out about this last summer but I had a new baby which made it almost impossible to go to a movie. I made it a mission to make sure to find out ASAP when they were going to start this summer. Most chain theaters are going to be doing free movies for kids this summer. Here are the links. We really only have a Regal Cinema in our area but that is good enough. Luckily, they have them on Tuesdays and Wednesdays (Tuesdays are my hubby's days off so it will work out great:) Make sure to go early!!!
