A check
Which of these is closest to a protected stretch as this lesson means it?
Going to bed at nine and getting up whenever the baby wakesSomeone else on duty in another room from ten until two, phone out of reach, agreed in advance what you will be woken forNapping when the baby naps during the dayHaving your mother stay over so there is someone in the house
Yes
The other three are all reasonable and none of them fixes the thing that is actually broken. Lesson two said the damage comes from the interruption rather than from the total hours, so an early night that still gets broken twice buys very little. What buys something is one stretch that is genuinely somebody else's shift, agreed beforehand so that you are not lying awake making the decision yourself.
