How do I adjust my BABYBJÖRN Baby Carrier Miracle to fit my growing baby?

Baby Carrier Miracle can be adjusted easily as your baby grows. There are adjustment instructions and a sliding buckle on the inside of the baby carrier's front piece. Adjust the buckle to fit your baby's height. The height setting is approximate. Hold the buckle flat. You may need to put some effort into it because, for safety reasons, the buckle is designed in such a way that it will not move too easily.
