The Choosing Healthy Eating for Infant Health (CHErIsH) intervention is a complex infant feeding intervention delivered at infant vaccination visits, alongside a healthcare professional (HCP) level implementation strategy to support delivery. The primary aim of CHErIsH pilot feasibility study is to collect and examine data on the acceptability and feasibility of the delivery of the brief infant-feeding intervention by HCPs to parents at child vaccination visits, and the strategy to support the implementation of this intervention in primary care for HCPs. Furthermore, half of all potential participants will be invited to provide maternal and infant biomarkers and/or take part in SWAT (study within a trial) which includes questions about infant feeding that were put together as part of a Core Outcome Set. These questions are important as they give a better understanding about what works and what doesn't. This will facilitate the refinement of the intervention and its implementation strategy, and inform the next step of the CHErIsH study, such as a definitive trial.
The Choosing Healthy Eating for Infant Health (CHErIsH) intervention is a non-randomised feasibility study of an infant feeding intervention and implementation strategy, with embedded process evaluation and economic evaluation. The CHErIsH feasibility study will address the following research questions: 1. Are the intervention content, delivery and implementation procedures acceptable to parents who will receive the intervention, and HCPs who will deliver the intervention? 2. Are the data collection processes, including mode and duration of data collection and outcome measures used, acceptable to parents and HCPs? 3. Is the intervention feasible to deliver in primary care practice, in terms fidelity of delivery and receipt of the intervention? 4. Is the study feasible in terms of recruitment and retention procedures and data collection? 5. What are the costs associated with the intervention and its implementation strategy?

Verbally delivered pre-specified infant feeding message. The messages focus on appropriate milk feeding and establishing complementary feeding and solid food introduction in relation to timing and practical guidance around processes of feeding and provision of additional infant-feeding resources including information leaflet, a magnet, an infant bib and access to an informational website.

Parent intervention feedback
Four-item measures of implementation outcomes including Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), Feasibility of Intervention Measure (FIM) will be used together to assess the acceptability, appropriateness and feasibility of the parent-level intervention (following intervention cessation). Scale values range from 1 to 5. 1 = completely disagree and 5 completely agree.
Time frame: Tp3= at infant's 13 month vaccination visit.

Intervention reach and recruitment
Number of invitations sent to parents, acceptances to participate, and refusals
Time frame: Tp1= baseline, prior to infant's 2-month vaccination visit; Tp2= by the infant's 6-month vaccination visit); Tp3= at infant's 13 month vaccination visit.
Appropriateness of parent data collection processes and outcome measures
Number of missing items self report questionnaires and follow-up rates
Time frame: Tp1= baseline, prior to infant's 2-month vaccination visit; Tp2= by the infant's 6-month vaccination visit); Tp3= at infant's 13 month vaccination visit.
Parent intervention fidelity
Checklist assessing intervention components received by parent (e.g., 'Did you receive a leaflet about infant feeding?').
Time frame: Tp3= at infant's 13 month vaccination visit.
Healthcare professional intervention fidelity
Checklist assessing intervention components delivered by HCPs (e.g., 'Did you provide parent with a leaflet about infant feeding?').
Time frame: Tp3= at infant's 13 month vaccination visit.
Estimate of resources and costs needed to deliver the intervention
Resources in relation the intervention will be identified. Costs incurred as a consequence of the intervention and implementation strategy will be identified. This will include all time and resources expended, and costs borne by Healthcare Centre including the training and time spent by healthcare professionals and administrative staff involved in the study.
Time frame: Tp3= at infant's 13 month vaccination visit.
