On level 26 (Entering Eekin) I just did a very slow double jump. I climbed to the top of the ladder and did a single jump. When I was about half the distance I hit A again and got to the bone.
I just went to level 47 (Road to Beaki-hai) and did the exact same thing. Top of ladder, jump and hold down A, hit A a second time when about halfway to the bone.
Hope this helps!
