Hi KarenK. You would end up with a lot of sourdough starter if you didn't discard some before feeding. It would soon become unmanageable. Once established you can maintain a smaller starter but you'll need to feed it without discarding any until you have enough for your recipe plus some to perpetuate the starter. Take a look at our blog, Maintaining a Smaller Sourdough Starter for instructions on how to do that. Happy baking!
