Our Early Movers longitudinal study found that adherence to the Canadian 24-Hour Movement Guidelines in infancy is low across demographic groups, impacting overall development. Early Movers is a parent-focused intervention designed to increase dissemination and activation of the 24-Hour Movement Behaviour Guidelines for the Early Years. It adapts an established Australian intervention called INFANT. An important first step is conducting a pilot study.

Our goal is to examine the feasibility and acceptability of the Early Movers intervention, a scalable, theory-based, parent-focused intervention designed to increase dissemination and activation of the 24-Hour Movement Behaviour Guidelines for the Early Years.

Primary Objectives:

1. Explore the feasibility of the Early Movers intervention protocol, including recruitment, retention, data collection, and procedures. Specifically, we will examine:

   1. the willingness of first-time parents to enroll and remain in the study,
   2. data collection completion rates, and
   3. the integrity of the protocol components to all work together and run smoothly.

2. Explore the acceptability of the intervention by parents and public health staff.

Inclusion Criteria:

-First time parents of infants who are aged 2 months 0 days through 2 months 30 days at baseline.

Exclusion Criteria:

• Parents who do not confidently speak or read English
• Infants who are regularly cared for by an adult other then their parent/guardian for a number of hours per week (e.g. full time child care)
• Infants born preterm (gestational age <37 weeks)
• Infants born underweight (<2500 g)
• Infants with a medical condition or health complication since birth that could impact their movement behaviours and/or development

Due to ethical reasons, individual participant data (IPD) will not be publicly available. De-identified data may be available to other researchers upon reasonable request.

Participants: While the families will not be told explicitly if they have been assigned to the intervention or control group, they may be able to determine their group based on the information regarding movement behaviours they receive/do not receive during their 2 month immunization appointment.

Research Coordinator: The research coordinator will be aware of the group allocations as they will be in charge of coordinating random assignment and have to schedule other measures based on their specific allocation.
