This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

1. To describe the forms of breastfeeding education and support for women with multiple pregnancies examined in randomised controlled studies.

2. To examine the effectiveness of different modes of interventions (e.g. face‐to‐face or over the telephone, or by different sorts of healthcare or lay practitioners), and whether interventions containing both antenatal and postnatal elements are more effective than those taking place in the antenatal or postnatal period alone.

3. To examine the effectiveness of education and support from different care providers and (where information was available) training for care providers.
