Here is an example of how the rise size setting could look like at the different ages. However, all children are different in how the shape of the body is, so this can vary from child to child.
When your child weighs 6 kg at about 2 months of age, it will most likely fit the Natural Snap-In one size diaper. It can be used for your child up to about 18 kg.
Natural Snap-In One size diaper:
2-8 months size small – rise size setting snapped all the way in.
8 months – 2 years size medium – rise snapped in the middle size setting.
2-3 years size large – diaper is unsnapped.
