*2.2. Consultative Approach to Early Intervention*

A principle of the RBM is that the intervention occurs between visits, so the point of visits with caregivers is to build their capacity to meet child and family needs when the professional is gone (i.e., during all the other hours of the week).

Family consultation involves the professional, usually a home visitor in the U.S. and other countries, working with the family to identify (a) why a child is not doing something, (b) what might be a viable solution, and (c) whether the strategy worked. This involves the professional asking many questions to find out what has being going on so far before making a suggestion [9–11]. He or she also asks the family whether they would like to try it out during the session and whether they think it is feasible.

Collaborative consultation to children's classrooms (CC2CC). Similarly, when professionals see "a child" in child care or preschool, they actually go to visit the teaching staff.

#### *2.3. Engagement Classroom Model*

The RBM includes procedures for running classrooms to promote child engagement, which we have dubbed the Engagement Classroom Model [12]. Implementers focus on five components:
