This plan is good. But sometimes provided the maid you hire is a fast learner. You don't have to worry about nanny not doing anything, u cannot have this mineset because ultimately if nanny do less and maid do more will only benefit u because ur ultimate care person for baby is picking up. Rather than everything let nanny do your maid just observe, by than u should feel even more worried because after nanny leave she still don't pick up any skills from her.
