When my son first started, he also doesn't need to 睇譜, he only followed the 'finger positions'1, 2, 3 etc, but as you can see the later chapters of 鈴木Book 1, it will gradually reduce the 1, 2, 3 indications, my son has no problems switching to pure 睇譜 after a few months.
But his teacher has been teaching him scales all along, although he still can't understand them fully, he can remember when to # or b in each scales.
