The impact of feeding experiences during infancy on later child eating behaviours

Abstract

Purpose of review: Individual differences in appetite and eating behaviours appear early in infancy. This review synthesizes recent research investigating the impact of feeding experiences during infancy on later appetite and energy intake regulation, and appraises the consistency and longevity of any effects.

Recent findings: Three themes of early feeding experiences were identified; breastfeeding, infants' first foods and caregivers' feeding practices. Recent findings suggest that breastfeeding alone is unlikely to promote better regulation of food intake later in childhood. It remains unclear whether the method of first food introduction (e.g., baby-led weaning vs traditional spoon feeding), or types of food introduced (e.g. ultra-processed foods), affect later child eating self-regulation. Randomised controlled trials (RCTs) on receiving guidance for responsive feeding showed some benefits; lower child body mass index z-scores in toddlerhood, parents reported less likelihood to pressure their child to eat or use food as a reward and lower emotional eating in the child.

Summary: There is little consistent new evidence for the lasting impact of any one specific infant feeding experience on later eating self-regulation. More RCTs using observed and measured behaviours, with longer follow-ups of children's eating behaviours, and those conducted across different populations are warranted.
