When is it OK to go to the movies with a baby? My daughter is already five months old. Is it OK if I take her during the weekend to see a daytime movie when it isn't so busy?
Yes, from a medical point of view, it is OK, as long as you aren't way up in the very front where the screen would be too close to her (and the sound too loud).
From a more practical point of view, how would you entertain her? The sound may or may not prevent her from sleeping, but how would you keep her from distracting the others who were there to see the movie?
