Because children with Achondroplasia (and other forms of dwarfism) grow differently than average height children, there are completely different Achondroplasia growth charts that the geneticists and pediatricians will be following. The arms and legs grow much slower, while the head grows faster and larger.
Because of these differences in growth, motor skills can also vary and there is a separate chart for tracking that as well.
Below are some common Achondroplasia growth charts for height, weight, and head circumference for male and females, as well as a motor milestones chart.
These charts DO NOT compare the growth between Achondroplasia and average height children. We already know there are differences, and like average height children, as long as they are meeting milestones when they should, that’s what is important.

Motor Milestones Chart for Achondroplasia

These are not the only Achondroplasia growth charts you may come across. These charts include the ones we were given by our geneticist, as well as a couple others that seem to be more common when doing online searches. You should always consult with your own specialists to decide which charts you should be using to monitor your child’s growth and development.
