Cover the floor with Newspapers. Gradually reduce the number of Newspapers, eventually leaving one in the tray. Be patient and act with kindness. If you yell at the dog, she's just going to look for a more secluded place for the toilet. When the baby is done doing his business on the paper - be sure to praise him. So the puppy will understand that there's only one place where you can spoil.
