i sight in my guns ( and most of my buddies guns ) 1 - 1 1/2 inch high at 100 yards, so at 200 yards your looking at less of a drop off below the cross hairs.

If your daughter is young enough to go on the youth hunt, she isnt ready to shoot 200 yards..... if you have not already gone over this stuff with her in pre-season and target shooting at 200 + then why take her and risk the animal, and risk her not enjoying the hunt over a lost animal.. something to consider.. personally with young ones id keep the shot inside 100 yards...
