How to make a good impression while babysitting
When going to the child's house, look presentable.
Wear an appropriate outfit, not something you might wear to a friend's house. Comb your hair, brush your teeth, and put on a nice body spray, or deodorant.
This will give the parents the impression that you take care of yourself. ( which is hopefully true! ) be sure to avoid shorts shorter than a few inches above the knee, very tight clothing, anything badly ripped, and miss matched clothes.
