Our shoes are measured and made based on this guide, therefore, it is best to measure baby's feet and add about 1cm for room to grow and make sure it is not too big especially if your child has started walking.
If you are unable to find a sizing that suits your child feet, feel free to contact us and we are more than happy to customise the sizing based on his foot measurements.
