How to Measure
For clothing, measure your child's height against a wall and note their weight — these two numbers are more reliable than age alone, since kids of the same age can vary widely in size.
For shoes, have your child stand on a sheet of paper, mark the tip of their longest toe, and measure the distance from their heel to the mark in centimeters. Re-measure every 2-3 months, since children's feet can grow half a size or more in that time.
