Description of intervention(s) / exposure
The Tiny Bites program is a primarily digital intervention that supports early childhood education and care (ECEC) services and primary caregivers of children aged <2 years with improving child nutrition, Tiny Bites will be delivered across approximately 18 months.

Strategies for ECEC services include:
-Participate in an initial educational outreach visit and support calls from a Health Promotion Officer throughout the duration of the intervention (educational outreach and facilitation). A health promotion officer located with the Local Health District will reach out via telephone to schedule the initial visit and any follow up calls at a time that is convenient to the service. These contacts could be conducted face to face, online or via the phone.
- The service supervisor will complete the web-based Tiny Bites self-assessment (approximately 15 minutes) and this will automatically generate a suggested action plan for implementation (self-assessment and action planning)
-Educators will be invited to participate in free training which will be delivered through pre-recorded (and live) 6 x 15-minute self-paced webinar modules covering infant feeding and responsive feeding practices and 1 x 20-minute self-paced webinar module covering nutrition conversations with primary caregivers, professionally presented by experts in the field of infant nutrition and communication (online professional development)
-Services will be asked to appoint an Infant Nutrition Champion (an educator in the infant room)

The strategies will support ECECs with:
- Updating policy and procedures around responsive feeding practices and infant feeding, including ongoing breastfeeding (where appropriate)
- Distributing bi-monthly online or paper communication to primary caregivers (approximately 9 over 18 months) using provided templates, which reinforce key themes from text messages and how the service supports these behaviours through their primary caregiver communication system
- Displaying physical resources including posters, stickers and flipcharts designed to remind educators about implementing best practice infant feeding and responsive feeding practices and to act as prompts to facilitate nutrition conversations with primary caregivers.
To assess adherence, the health promotion team will track number of contacts and what was delivered in each session. To maximise adherence, multiple contacts and flexible delivery modalities will be offered to ECECs. We will gather online analytics to monitor completion of webinars and use of the online elements..

Primary caregivers will receive:
-Regular text messages (approximately weekly to fortnightly throughout the 18-month period). These messages will be broadly tailored to child developmental milestones and will be one-way messages.
- Monthly/bi-monthly digital newsletters summarising resources and text messages (these newsletters will also be delivered to nominated individuals who may be involved in feeding children, such as grandparents/extended family members).
- A number of communications from the ECEC service will be distributed to primary caregivers which reinforce key themes from text messages and describes how the service is supporting these behaviours. These may vary from centre to centre.
- Access to a webpage with a collection of infant feeding and responsive feeding digital resources. Some text messages and digital newsletters will include links that direct parents to this webpage and/or specific resources.
- Access to infant feeding and responsive feeding webinars developed by experts via links in the text messages. This will be recorded versions hosted on the Tiny Bites program. This will be similar to that accessed by the childcare providers in terms of length and duration.

We will collect data related to parent opening of text messages and accessing links using online analytics. We are not able to access individual parents accessing of the webinars however will monitor the number clicking on the link to the online recording.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Services will be randomly assigned, following all service baseline data collection, An independent statistician will generate the randomisation schedule and this will be centrally allocated (and concealed) following baseline data collection. Following random allocation, services will be notified of their group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Services will be randomly assigned to the intervention or to a usual care control group in a 1:1 ratio. Randomisation will be stratified by socioeconomic status (SES) based on Socio-Economic Indexes For Areas (SEIFA) classifications using the ECEC service postcode, given the association of SES with primary outcomes. We will also use block randomisation (2, 4 or 6) to ensure group allocation is approximately equal. The sample will also be stratified to ensure services with a high proportion of Aboriginal and Torres Strait Islander child enrolments (>10%) will be assigned to the intervention or control group in a 1:1 ratio.

Efficacy
Statistical methods / analysis
Based on previous studies, the standard deviation is approximately 1.0 and mean BMI z-score is approximately 0.41. To detect an absolute difference of 0.26 in BMI z-score (considered clinically significant at a population level with 80% power and two-sided 5% significance level and intracluster correlation coefficient (ICC) of 0.02, a sample size of 270 per group (540 total, approximately 60 clusters of 9 dyads) will be recruited. As an intention-to-treat analysis will be undertaken as the main analysis (participants analysed according to the group as randomised), we have not accounted for attrition.

Consistent with best practice, the primary analyses will be undertaken under an intention-to-treat framework, using multiple imputation to account for missing data. For the primary outcome, between-group differences will be assessed for paired data using 2-level hierarchical linear regression models (for continuous data). Models will be adjusted for services-level clustering through a random effect and controlled for baseline measures and service’s SES.

To assess differences between groups for secondary outcomes, linear regression analyses will be conducted (for continuous outcomes). Models will be adjusted for services-level clustering and any stratified variables through a random effect and controlled for baseline measures.

Summary
Brief summary
This study seeks to assess the effectiveness of an 18-month digital health intervention (Tiny Bites) targeting infant feeding practices, delivered to ECEC educators and primary caregivers of children aged between 4-12 months (inclusive) relative to a usual care control group. We hypothesise that children in the intervention group will have a 0.26 lower BMI zscore compared to those in the control group.
We will recruit 60 early childhood education and care services and 540 carer/child dyads. Services will be randomly assigned to intervention or control in a 1:1 ratio. To improve infant feeding practices, services allocated to the intervention group will receive access to an online portal (which includes a self-assessment and webinars around infant nutrition) and support from health service staff. Parents in the intervention group will receive text messages tailored to their child's age around infant feeding. After delivering the intervention for 18 months, we will compare the BMI zscores of children in the intervention group to the control.
