My dd 2 3/4 will at various times say "That is hurting my ears." Sometimes, I think she says it when she doesn't like the sound. Example: She loves music, but not all music. I will be playing the music while driving and she will tell me to turn it down or say that it is hurting her ears. I will turn it down and she will say it again. I will turn it down some more, and she will keep complaining back and forth until the music is off. Sometimes, I know it is a game, but I think it always starts with her discomfort with the music.
I sometimes when I press her she will say that she has a headache. I do not know whether she really has a headache, or if she is just saying that. She is at a stage that, although she talks very well, I am not always certain how much weight to give her when she says something. All things considered I think I will play with the idea that my LO might be somewhat sensitive to noise. Thank you for the post, it gives me something to think about.
