My  daughter "was" afraid of heights >>>>   but wanted to see what was in the attic.    9ft ceiling scuttle hole and a 8ft ladder,.  Her 3yearold little brother could make it, she could too.  She would hold onand shiver like a wet cat.  She made it up but froze  on the way down.  "OH-NOOO its going to fall over"    I said " its in the hallway ther is no way it can tip over"    I then proceded to tip the ladder bouncing it off each wall  ( with her on top)  and  after I stopped,  and, she calmed down,  She then realized she was OK, and  NOW she will go up/down a ladder if necessary.  Little brother(s) wanted to play "bounce off the wall after that.
