Sonu Niigaam started singing at the age of three and he feels that if a child shows interest in any art form at a very tender age, he should be trained for it.

"If kids start following a particular art form at a young age, then it helps them. Even I have been singing ever since I was 3-and-half years old. This is the best time to learn something," the 38-year-old singer said here at the Lions Gold Award function where both he and his four-year-old son were honoured.
