What to do with a six-year-old who is frustrated from learning to tie his shoes? Make him do it again. Grit and Grin and tie it again. And again. And again. OR end up tying shoes for a 30-year-old man (???) Yeah. No.
Each of my three older children are different in this way. Maestro has had a lot of experience at things coming relatively easy for him. With music, he has never had to really press through frustration because he "gets it" on the first or second try. It's just his thing. Smeagol, on the other hand, has long had to work for every. single. step.
