Poor dd1 (13) had a fall on the way to school this morning and cut and grazed both knees.
The school cleaned her up a bit and put plasters on but told her that she should get me to look at them tonight to see if she needs stitches. 
One knee is grazed and looks like it has bits of gravel in. The other has a longish cut which is gapping a bit and still bleeding slightly. It also looks a bit dirty.
Any advice on how to clean and dress them? Or should I get her seen by a doctor/nurse?
