Daughter Will Not Learn Music…please Help

My daughter did three years of Carnatic music. She has a good voice and I had put her with a very good teacher who is actually nice but quite strict about practice etc.
I tried my best with DD but sooner or later she lost interest.I am also good in singing.

My cosister sings well and she has a daughter who she had enrolled in Carnatic music.

I am going to be very honest but there was a slight competitive spirit between us as both wanted our daughters to excel plus we were trying our best.

for some months we took a break from music as my daughter was getting stressed.I am hoping to put her with another teacher.

two days back we had a function and once it ended people asked some
Kids to sing. My cosister immediately made her daughter sing a very difficult song and she also did with her and everyone clapped. When my daughter was asked to sing...she said no and she shyly sang “sa re ga ma...”

I was aghast. Three years of music and spending so many dollars and this?????
Plus the smirk and satisfaction of some win in my cosister face was very hard to fathom. I felt so embarrassed and was in tears. I just smiled and came back home.

Last two days I couldn’t sleep. In my family there are so many ladies who cannot sing but their daughters and even sons are well versed in Carnatic music.

Me on the other hand is trained in Carnatic music and has been training my kid and my daughter hates music and refuses to learn. I feel absolutely terrible.

I know IL friends will tell me not to compare and kids have other interests and even I know that but am just unable to digest and accept the fact that my kid will never learn Carnatic music.

I just want to accept the fact and move on but don’t know how.The sarcasm on my cosister face is so tough for me to handle also.

Also am very worried next teacher (if it happens) will start from the beginning for music…

How do I get over this? Please understand my feelings and make me see the fact and the right things..
