Hi Judy! To have enough starter for your five loaves and enough to keep it going, you'll have to have six cups of starter to start baking. To get those six cups you would feed 2 cups (16 ounces) of your starter with 2 cups (16 ounces) of water and 4 scant cups (16 ounces) of all-purpose flour. It will take a few hours at room temperature for that large mixture to get nice and bubbly and ripe and ready to make your dough. To make sure you always have at least 2 cups of starter in your fridge in order to do this, change your regular feeding from 4 ounces each of starter, flour, and water, to 6 ounces of each. This would be 3/4 cup starter + 1 1/2 cups flour + 3/4 cups water. This will be your regular starter that lives in the fridge all the time. It will give you enough to use the 2 cups in your mixture when you're ready to make bread, and leave you enough to feed and keep going.
