This secondary analysis of a randomized controlled trial evaluated the growth and dietary intake of 144 infants aged 5 to 12 months following baby-led weaning (BLW) versus conventional weaning (CW). At 9 months, BLW infants had higher sodium intake (437 mg vs 294 mg; P < .001) and different macronutrient distributions, but no significant differences in growth outcomes were observed between the two groups.

Key findings

  • At 9 months, BLW infants had higher sodium intake (437 mg vs 294 mg; P < .001).
  • BLW infants had a higher percent energy from fat (47% vs 43%; P < .001) and lower from carbohydrates (43% vs 50%; P < .001) at 9 months.
  • No significant differences in rapid weight gain or growth z scores were observed between BLW and CW.

Why it matters

Understanding the impact of different complementary feeding approaches on nutrient intake and growth is crucial for pediatric care. This study suggests that both BLW and CW can support similar growth outcomes, which may influence feeding recommendations for infants.
