Since the braces went on she wears it in the infield but mostly because she can't seem to get comfortable with a mouthguard. Before that only at the corners.
DD suffered an eye injury and was required to wear one by the DR, or not play. So she got use to it, but liked the Rip It over the game face. A partial torn retina from a ball hitting her eye socket , makes you take a different view. It was a soccer ball not a softball , so it doesn't take a hard object. She had goggles for soccer, during that time frame. Hated the goggles.
All infield. Mostly because it's been engrained into her to practice like she plays, and it's just too silly to have a kid running back and forth to get their mask at practice. Glove goes on, mask goes on, it only comes off if she's in the outfield.
