Ecological Momentary Breastfeeding Intervention

The EMI-I messages will be delivered in sequence over three months. The content, frequency, and timing of the messages will be determined by participant preferences, as determined during the baseline evaluation, as personalisation is central to such cognitive and behavioural changes. The messages will mainly be text-based, but other forms such as videos will also be used, depending on the needs of the participants.

The nurse will initiate 10-15-minute chats via an online platform (e.g., WhatsApp) after all instant messages for each session have been delivered. The nurse will guide the participants to set goals for breastfeeding. Any anticipated barriers will be discussed. The participants can also initiate the chats. While there is no limit to the number of chat messages, nurse-led real-time support messages will be provided during working hours (i.e., 9 am-6 pm on weekdays).
