We have sort of the same problem at our house at the moment except mine is a cheerleader. It is seriously driving me batty. First, I NEVER thought a dd of mine would be into this. Did not see that one coming... Second, who is this tall blonde girl with pompoms running around my house yelling, waving her arms around and jumping up and down??? Funny, I don't remember letting this person into my house.:LOL
I'm hoping that this will run it's course and won't be an issue again. For now, I'm just telling her that I know she needs to practice, but please do it where I can't hear it, there is enough NOISE in my life (I have a 4 and 5 yo too.) The sting is taken out when I remind her that I'm going to see her at all of the games and when she learns something new, I do
want to see it. Just not repeatedly.
She knows that I like quiet, lots of noise just freaks me out and I think she respects that. Right now, she's just so excited and, well, cheery
Maybe with some gentle explaining that you're sensitive to noise your dd will understand. Some people like soft back massages and others like vigorous ones, but massages are always a good thing, just like singing. Maybe suggest practicing away from you, but always listen to what she has been working hard on or a new song. I hope your situation works itself out, I know how touchy it can be.
Come to think of it, I think I drive my kids nuts singing all of the time.
