Chill-out in Pregnancy (CHiP) is a group-based
antenatal support programme underpinned by
self-regulatory theory. Like MB, it is designed
to be offered between 20–30 weeks’ gestation.
The format of CHiP is similar to MB, with the same number of sessions and delivery approach,
but there is no content related to infant mental
development or parent–child interaction. Each
session incorporates a subject related to maternal
wellbeing like those in MB. Like MB, there is an
emphasis on practical activities, viewing videos
and discussion, as well as a guided relaxation
session at the end of each week (Figure 2).
