The time period is sufficiently described (hours, minutes). However, the time period is not for a specific event (average time actively sucking) and the time period is not continuous as it is for only the days in the past 4 weeks that the baby was breast fed.

Example 4
Questionnaire: Mother and Home (ALSPAC) question E17
Response to ‘On average how many hours per day do you spend doing the following?’ is entered as a numeric answer (see Numeric Answers for further guidance) [Add link]. This question fails all three criteria for a duration answer. The time period is not for a specific event (average time spent), the period queried is not continuous, as each of the activities in the question may be done at several different points during a day, and the single time response of ‘hours’ does not sufficiently describe a discrete time period.
