Interventional
Description of intervention(s) / exposure
Graduated Extinction (gradually extending the time between the infants' cry and the parents' response to the infant: response time night 1, 2-6min; night 2, 3-7min; night 3, 5-15min; night 4, 10-20 min; night 5, 15-25 min; night 6, 20-30min; night 7, 25-35min [duration of treatment =1 week]) vs. Bedtime Fading (bedtime restriction therapy: gradually reducing infants' time in bed to more closely match their total sleep time, 15-min changes to bedtime made once per night until desired bedtime is reached [duration of treatment=1 week]). Parents supported with 24/7 mobile phone support during treatment, when needed.

Comparator / control treatment
Sleep Education (educating parents about infants' average nocturnal sleep time, individual difference in sleep obtained, sleep architecture (eg, sleep stages) and napping). Administered in a single 50-minute session on an individual basis.
Control group
Active

Outcomes
Primary outcome [1] 287619 0
Sleep (including sleep onset latency and wake after sleep onset, both in minutes; and the number of nocturnal awakenings). Outcome assessed with parent-completed 7-day sleep diaries of their infant's sleep, as well as a activity monitor worn on the infant's ankle.
Timepoint [1] 287619 0
Pre-treatment, 1 week after beginning treatment, 1 month after, 3 months after and 12 months after.
Secondary outcome [1] 298538 0
Infant stress (salivary cortisol).
Timepoint [1] 298538 0
pre-treatment, 1 week-, 1 month-, 3 months- and 12 months after treatment.
Secondary outcome [2] 298540 0
Parental (self-reported) stress, as measured by the Stress subscale of the Depression Anxiety Stress Scale (Short Form).
Timepoint [2] 298540 0
pre-treatment, 1 week-, 1 month-, 3 months- and 12 months after treatment.
