The purpose of this study is to investigate if a postnatal public health breastfeeding intervention relying on the importance of the psychosocial factors can prolong the period with exclusive breastfeeding duration among mothers who want to breastfeed.

Breastfeeding is a complex learned behaviour and not a capability which comes naturally with motherhood. Different types of professional recommendations have been used to support the new mother in this process.

Randomised studies have shown that postnatal support can influence the breastfeeding duration positively. Various studies has offered different kinds of interventions with home visits and/or telephone calls as the generally used approach, but the proper follow-up on the breastfeeding support in the postnatal period after the mother leaves the hospital is not yet clear.
