Development stage

Development stage is when something is still growing and changing. Just like you are growing taller and learning new things every day, many things around you are also still growing and changing. For example, a baby is in the development stage because they are still learning how to crawl, walk, and talk. Plants are also in the development stage because they are still growing bigger and getting stronger. Even buildings and cities can be in the development stage if they are still being built or improved. So when you hear someone say something is in the development stage, it just means that it is still changing and getting better!
