So I have a question about my fluffmuffins. I've been giving them probiotic water as well as plain. I made up a gallon the first day and have been giving them a fresh quart every morning. Tonight I went to make up another batch and see on the envelope it says make up a fresh batch DAILY. Each packet makes a gallon and costs close to $4 each. Seriously? Can I refrigerate it or do I really have to throw 3 quarts away every day?
