I'm hoping that the power of MN will come up with some alternative ideas.
My 2yo DS grazed his forehead about 5 weeks ago. It was a tiny graze and should have healed quickly. But DS is a little picker - can't keep his fingers off it - so it doesn't get a chance to form a scab and heal, it weeps and bleeds but isn't infected. It is now a much larger wound and looks like it will leave a permanent scar.
If I put a plaster or dressing over it (to protect it from the picking), he just picks at that too until he's removed it (in minutes). It is right up near the hairline, so difficult to stick anything over the hair.
Unless I find a new approach, I can't see this healing any time soon.
Many thanks
