This study aims to investigate breastfeeding, infant feeding behaviours, and attitudes to feeding amongst women with eating disorders (ED) and healthy controls (HC). Women with active ED (C-ED; N = 25), past ED (P-ED; N = 28), and HC (N = 46) were recruited in pregnancy and followed up longitudinally. Post-natally infant feeding behaviour was investigated at 8 weeks, 6 months, and 1 year and parental modelling at 1 and 2 years. Women with P-ED and C-ED reported higher concerns about their infant being/becoming overweight compared with HC, respectively, at 8 weeks and 6 months and 6 months only post-partum. Women with P-ED showed less awareness of infant hunger and satiety cues compared with HC at 8 weeks. Despite few differences between ED and HC, both P-ED and C-ED predicted maternal attitudes and worries about child's eating. These are likely to impact on child's growth and later eating behaviours and might impact on the intergenerational transmission of ED.
