The important health advantages of breastfeeding more than justify the introduction of these provisions. These advantages are maximised when breastfeeding is sustained for longer periods. Research commissioned by a number of health boards shows that returning to work can influence the decision of Irish women to cease breastfeeding. For example, in a study commissioned by the Midland Health Board in 2000, 30% of respondents gave "returning to work" as the reason for ceasing breastfeeding.
