My daughter loves movies! She did not really like the first one we went to, though. I think it kind of scared her. After that first one, she would cry when it was all over because she thought it was so neat to see the movie that big on the screen. Thankfully we have gotten past that phase, too! Definitely bring something to cover his ears. Some theaters are worse than others - a lot of the time we wait for the movies to come to the dollar theater here before we go see them and their sound is awful! Always WAY too loud, even for me! If you have a pair of earmuffs or headphones or something, otherwise we have used a hat like Deb suggested. Much easier than sitting with your hands over his ears to muffle the sound for an hour! lol
We usually take her blanket too, again, because it is a cheap dollar theater and usually kind of cold. The blanket does double duty to be able to cover her if it is cold and to cushion the booster seat so she can see. At the 2 year old point I would sneak in my own snacks for her (yeah, bad mommy sneaking in the snacks...) usually goldfish crackers or something like that because she didn't like popcorn yet. Now that she is three, she changed her mind and likes popcorn so I don't bother with that as much now, we usually just get the kiddie meal thing with the popcorn and drink and share. Since this is his very first movie, do be prepared to leave early. He could not like the experience at all. I think that was another reason we did the dollar place at first because then i wouldn't lose so much money if she hated it! I remember taking her to see the Veggie Tales movie with my mom and it is such a fun memory! She was just totally enthralled by the movie - I don't think I had ever seen her sit for that long without squirming around. hee hee Just have fun and I hope your little guy enjoys himself!
