Parent reported sleep characteristics will be measured with the Brief Infant Sleep Questionnaire-Revised (BISQ-R) at Time 1, 2, and 3. Each BISQ-R subscale and total score are scaled from 0 to 100. The BISQ-R has been validated against sleep diaries and actigraphy to elicit parent reports of children's sleep patterns (daytime and nocturnal sleep duration, frequency of awakening, sleep latency), sleep habits [sleeping arrangements, parent-child interactions about sleep (e.g., bedtime behaviors, behaviors related to nocturnal awakenings)], sleep difficulty (i.e., bedtime resistance, nocturnal awakenings, and snoring, a risk factor for sleep apnea]. Questions include information about bedtime routine activities and consistency. Approximate time to complete: 10 minutes. The investigators anticipate an improvement in the three subscales and total score of the parent-reported sleep characteristics after receiving the SWBW intervention.

Data on the number of vocalizations and level of noise will be collected using the Language Environment Analysis (LENA) recorder and software that measures frequency of vocalization/verbalizations and conversational turns in children. The LENA device will be worn inside of a vest provided to each child that will be worn on top of the children's clothing. Digital audio recordings will be collected for four days at Time 1, 2, and 3 while the child is wearing the actigraph. Software algorithms parse the continuous audio stream into discrete, variable-length segments that are matched to pre-defined sound models, separating speech-related sounds from environmental and other sounds to compute count estimates of adult words, child vocalizations, conversational turns, and decibel levels.

Parental Interactive Bedtime Behavior Scale (PIBBS) is a 19-item Likert-type parent questionnaire that measures the interactive behaviors caregivers use with their children at bedtime. A total score is calculated as percentage. Approximate time to complete: 5 minutes. The survey will be collected at Time 1, 2, and 3. This survey will be used to generate hypotheses for future clinical trials with a larger sample size. The investigators anticipate that parental interactive bedtime behaviors will improve upon completion of the SWBW intervention.

The BISQ-R has been validated against sleep diaries and actigraphy to elicit parent reports of children's sleep patterns (daytime and nocturnal sleep duration, frequency of awakening, sleep latency), sleep habits [sleeping arrangements, parent-child interactions about sleep (e.g., bedtime behaviors, behaviors related to nocturnal awakenings)], sleep difficulty (i.e., bedtime resistance, nocturnal awakenings, and snoring, a risk factor for sleep apnea]. Approximate time to complete: 10 minutes. The investigators anticipate an improvement in the total score of the parent-reported sleep characteristics after receiving the SWBW intervention.

The Parenting Stress Index 4-short form (PSI4-SF) is a 36-item parent self-report questionnaire that assesses the level of stress in the parent-child system with a reading level of grade 3.5. It has been well-validated as a measure to predict parenting behavior in the U.S. and more than 20 countries. There are three subscales, parental distress, parent-child dysfunctional interaction, and difficult child, that combine to form a total stress scale Approximate time to complete: 10 minutes. The survey will be collected at Time 1, 2, and 3. The scores range from 36-180. The investigators anticipate that the parenting stress will improve after receiving the SWBW intervention.

The Center for Epidemiological Studies Depression Scale (CES-D) is a brief measure of depressive symptoms that consists of 20 items selected from other depression scales. Each item is rated on a scale from 0-3 in terms of frequency of occurrence during the past week. The total score may range from 0-60, with a score of 16 or more indicating impairment. The reliability of the CES-D has been documented with high internal consistency reliability, acceptable test-retest stability, and construct validity in both clinical and community samples and has been used successfully (alphas = .85-.83) with urban parents. The survey will be collected at Time 1, 2, and 3. The investigators anticipate that the self-report of the parents' depressive symptoms will improve after receiving the SWBW intervention.

Self-efficacy for Parenting Tasks Index - Toddler Scale (SEPTI-TS) will be used to measure parental self-efficacy, a key factor in social cognitive theory. The SEPTI-TS is a 51-item questionnaire with seven subscales: emotional competence, sensitive response, protection, discipline/limit setting, play, teaching, and instrumental care/structure/routines. The internal consistency in a study using social cognitive theory to assess parental efficacy in toddlers was good (alpha=0.88). Approximate time to complete: 5 minutes. The survey will be collected at Time 1, 2, and 3. The score ranges from 26-156.The investigators anticipate that parents will report increased parental self-efficacy upon completion of SWBW.

Knowledge, attitudes, self-efficacy, and beliefs about sleep in children (KASB) will be administered. There are seven self-efficacy items. The survey will be collected at Time 1, 2, and 3. The score ranges from 0-76. The investigators anticipate that parental knowledge, attitudes, self-efficacy, and beliefs about their children's sleep will improve upon completion of the SWBW intervention.

The sleep characteristic of nap timing will be measured with the Respironics Actiwatch AW2, an accelerometer placed on the toddler's ankle. Reliability for actigraphy in toddlers ranges from .67-.85 when measuring sleep duration. The toddler will wear the water resistant Actiwatch 2 for seven 24-hour periods at Time 1, 2, and 3. The investigators hypothesize that toddlers' day-to-day nap variability will be reduced after receiving the SWBW intervention.

PROMIS- Parent Sleep short form is a 7-item survey developed from the item bank of the Patient-Reported Outcomes Measurement Information System (PROMIS™) Sleep Disturbance (SD) to identify sleep disturbance in adults. The survey will be completed at Time 1, 2, and 3. The score ranges from 8-40. The investigators anticipate that parents' self-report of sleep disturbances will improve upon completion of the SWBW intervention.

Future/Hope Scale: The 12-item Trait Hope Scale (also referred to as The Future Scale) assesses hopefulness. It has two subscales: Pathways and Agency. It has a Cronbach's alpha of between .74 to .84, depending on the population. The Cronbach's alpha for the Agency subscale is between .71 to .76, and between .63 to .80 for the Pathways subscale. The survey will be collected at Time 1, 2, and 3. The score ranges from 8-64. The investigators anticipate that parents will report increased hopefulness upon completion of SWBW.

Parents will complete a sleep diary to record their toddler's naptime, bedtime, duration of sleep, sleep location, and bedsharing for the 7-day period when the toddlers wear the Actiwatch 2 (see below). These data will assist with the actigraphy scoring. The sleep diary will be collected at Time 1, 2, and 3.

SF-36 (general physical and mental health): The SF-36 is a multi-purpose survey designed to capture adult patients' perceptions of their own health and well-being. Based on a much longer survey developed in the 1980's by Ware, J.E., the SF-36 has 36 items grouped in 8 dimensions: physical functioning, physical and emotional limitations, social functioning, bodily pain, general and mental health. It is a generic measure, as opposed to one that targets a specific age, disease, or treatment group. In one of the first validity studies, the instrument was acceptable to good estimates of reliability, support for construct validity, and support for convergent and divergent validity for 4 of the 8 dimensions. The survey will be collected at Time 1, 2, and 3. The score ranges from 0-100. The investigators anticipate that the parents' self-report of their well-being will improve upon completion of the SWBW intervention.

We will measure the quality of parent-teacher interaction using the INVOLVE questionnaires with both the EHS teachers and parents. The 11-item parent-reported Parent-Teacher Involvement Questionnaire (INVOLVE-P) was adapted for use with parents of children in Head Start programs to evaluate parents' involvement with their children's education and activities at home and at childcare. As a companion measure, the 20-item teacher-reported Parent-Teacher Involvement Questionnaire (INVOLVE-T) requires teachers to rate parents' involvement in their child's education, and their frequency of contact with teachers and school personnel. There are three subscales were created: Teacher Bonding with Parent, Parent Involvement in Education, and Parent Involvement with Teacher. These surveys will be collected at Time 1, 2, and 3. The range of scores for the INVOLVE-P is 0-104; the range of scores for the INVOLVE-T is 0-80.
