Shoe size baby conversion

Changing the shoe size of the baby is a little more difficult than determining the size of the baby. The shoe size baby is not the number of centimeters of the foot. But there is a way to find this out.

Be the first to put your baby on a pair of socks. Then you leave your baby on a sheet of paper and you draw a pencil around the foot. So you make a kind of footprint on paper. You measure the distance between the big toe and the heel. Here you count a half to a whole centimeter. Then you take the diagram below to figure out the size. If your baby does not have exactly the number of centimeters that is indicated around you upwards. Better too big shoes for the baby than too small!
