My younger daughter shows interest in music. There is no perfect time to discover the talents hidden inside so give all the support that your child needs. Last year, when she told me that she wants to be a swimmer, I enrolled her to a swimming class and dedicated my time to support her in this field but she became lazy afterwards. Swimming isn't really her craft. With the skills that she acquired, she lose nothing because swimming is not only a sport but also a survival skill. Now that she seems to love another field that is music, I might enroll her again to discover what she really wants to do in life. I might get her a a guitar to bring out her ability and hidden talent. There is no harm if she learns how to strum a guitar just like when she's still into swimming, because it is about developing the talent inside her and having some fun at the same time.
