I just want to AW J for a minute. We decided to take him to his first movie (in a theater) today. We went to see Monsters University and he did so well! He sat in the seat the whole time (I had to keep my leg on the edge, as he was too light to keep the seat from folding up at times, but he was quiet and still the whole time. During the previews he was a little movie critic and at the end of each he would say, "Not funny". We took our nearly 5 month old too, and he did great too!
For the record, as soon as we got out of the movie, he had TONS of energy to burn so he was all over the place, but while we were in there, he was great.
