Despite its health benefits, only 63% of women in Scotland will attempt to breastfeed. Our aim was to investigate future feeding intentions and attitudes in adolescents in the south east of Scotland. Of the 757 adolescents questioned, 78.8% of girls (n = 430) and 61.6% of boys (n = 130) stated an intention to breastfeed or to encourage their partner to breastfeed. Knowledge of being breastfed as an infant was the only factor associated with a higher Iowa Infant Feeding Attitude Score and proportion that either intend to breastfeed or support breastfeeding in the future.
