Does Small White Patches On The Body In Kids Indicate Vitiligo?

ABOUT A MONTH AGO I NOTICED A SMALL WHITE CIRCLE (DISCOLORATION) ABOVE MY 6-YEAR-OLD DAUGHTER'S UPPER LIP. LAST NIGHT I FOUND 3 WHITE CIRCLES (2 LOOK TO BE AROUND A FRECKLE OR MOLE) ON HER THIGH, ONE ON HER SHOULDER AND ONE NEAR HER TEMPLE/HAIRLINE. COULD THIS BE VITILIGO? SHOULD I TAKE HER TO SEE OUR PHYSICIAN? I'M A BIT NERVOUS ABOUT THIS.
