Parents of infants and preschoolers, especially dual-income and time-constrained households

TL;DR

  • ·Across 17 studies and 18,000+ children, sharing family meals at least three times a week was associated with an OR of 1.24 for healthy eating habits — a moderate but real effect that builds gradually over time
  • ·Screens at the table cancel most of the benefit; the quality of the shared meal — conversation, absence of distraction, consistent routine — matters more than simply having people physically present
  • ·Three to four screen-free shared meals per week with some conversation is a sustainable baseline that maps reasonably well onto the effect sizes in the literature

This article works through what longitudinal studies and meta-analyses on shared family meals actually show.

  • Nursing, pumping and bottles run on a timer, with side and volume recorded alongside.
  • Solids build up into a list of what's been eaten, so a first-time food is easy to spot.
  • Height, weight and head circumference are drawn over national reference curves.
