Insights
Baby-led weaning (BLW) is a safe infant feeding method. This study found BLW did not increase iron deficiency or choking risk compared to traditional spoon feeding (TSF).
Area of Science:
- Pediatric Nutrition
- Infant Development
- Public Health
Background:
- Baby-led weaning (BLW) is an infant-led approach to complementary feeding gaining parental interest.
- Limited scientific research exists on BLW's impact on infant health outcomes.
- This study investigates BLW versus traditional spoon feeding (TSF).
Purpose of the Study:
- To assess growth parameters in infants following BLW compared to TSF.
- To evaluate hematological status and iron intake in infants using different weaning methods.
- To determine the safety of BLW regarding choking incidence.
Main Methods:
- A randomized controlled trial involving 280 infants aged 5-6 months.
- Infants were allocated to either BLW or TSF groups.
- Growth, hematological parameters, and iron intake were measured at 12 months.
Main Results:
- TSF infants were significantly heavier than BLW infants at 12 months.
- No significant difference in iron intake from complementary foods was observed between groups.
- Hematological parameters and choking incidence were similar in both BLW and TSF groups.
Conclusions:
- Baby-led weaning is a viable complementary feeding option.
- BLW does not elevate the risk of iron deficiency, impaired growth, or choking.
- This is the first randomized controlled trial to demonstrate these findings in breastfed infants.
Background:
Baby-led weaning (BLW) is an approach to introducing solid foods to infants that gives control of the feeding process to the infant. Anecdotal evidence suggests that BLW is becoming popular with parents, but scientific research is limited to a few publications. This study assessed growth, hematological parameters and iron intake in 6-12-month-old infants fed by traditional or baby-led complementary feeding.
Methods:
We recruited 280 healthy 5-6-month-old infants allocated to a control (traditional spoon feeding; TSF) group or an intervention (BLW) group in a randomized controlled trial. Infant growth, hematologic parameters and iron intake were evaluated at age 12 months.
Results:
Infants in the TSF were significantly heavier than those in the BLW group. Mean weight in the BLW group was 10.4 ± 0.9 kg compared with 11.1 ± 0.5 kg in the TSF group. There was no statistically significant difference in the iron intake from complementary foods between the BLW (7.97 ± 1.37 mg/day) and TSF (7.90 ± 1.68 mg/day) participants who completed the diet records. Hematologic parameters were similar at 12 months. The incidence of choking reported in the weekly interviews was not different between the groups.
Conclusions:
To the best of our knowledge, this is the first randomized -controlled study to have examined the impact of weaning method on iron intake, hematological parameters and growth in breast-fed infants. BLW can be an alternative complementary feeding type without increasing the risk of iron deficiency, choking or growth impairment.
