Hearing aids take some time to get used to. Everything is so loud to her now .... If someone is crying or yelling it will be ear piercing to her..... If blocks are being banged together it's deafening.... And even though you are hearing the same as she is it will be worse for her because she's not used to it. all the noise of the kids playing can be overwhelming and I'm guessing the reason for the tantrums ( if they started since the arrival if hearing aids) also musical instruments would probably not be a good idea..... And when outside the wind would be terrible .... Have you ever watched the news when a reporter is broadcasting live from a hurricane or tornado site and the wind is so bad that all you can hear is horrible static from the microphone and the odd word from the reporter ???? That's what it will be like for her !!!! So make sure when you are outside on windy (even light wind) that she has a hat on that covers her ears. I feel for this kid
