Who is Doctor Slop from The Life and Opinions of Tristram Shandy and what is their importance?

Dr. Slop is Walter's choice to deliver Tristram. In the end, Walter calls him to the house to act as back up. At the home awaiting Tristram's birth, the doctor talks to Walter and Toby about religion and childbirth, showing a fondness for arguing. He sees himself as a figure of authority and is upset when he has to go upstairs to see the midwife, as he thinks she should come down to see him. His forceps are responsible for damaging Tristram's nose.
