Abstract

Background: A baby-led approach to weaning (BLW) encompasses self-feeding and self-selecting graspable foods, offering an alternative to traditional weaning (TW). This cross-sectional study explored adherence to characteristics of BLW and differences in food group exposure and nutrient intake between babies following either TW or BLW.

Methods: Nutritional data were collected via multiple-pass 24-h recall, following parental completion of an online survey.

Results: Infants were grouped according to age (6-8 months; TW [n = 36] and BLW [n = 24]) and (9-12 months; TW [n = 24] and BLW [n = 12]). BLW babies were more likely to be breast fed (p = 0.002), consumed a higher percentage of foods also consumed by their mother (p = 0.008) and were fed less purees (p < 0.001) at 6-8 months. TW babies were spoon fed more (p ≤ 0.001) at all ages. Amongst babies aged 6-8 months, total intake (from complementary food plus milk) of iron (p = 0.021), zinc (p = 0.048), iodine (p = 0.031), vitamin B12 (p = 0.002) and vitamin D (p = 0.042) and both vitamin B12 (p = 0.027) and vitamin D (p = 0.035) from complementary food alone was higher in babies following TW. Compared to TW, BLW babies aged 6-8 months had a higher percentage energy intake from fat (p = 0.043) and saturated fat (p = 0.026) from their milk. No differences in nutrient intake were observed amongst infants aged 9-12 months. Few differences were observed between groups in their number of exposures to specific food groups.

Conclusions: TW infants had higher intakes of key micronutrients at 6-8 months, although there were few differences in nutritional intake at 9-12 months or food group exposure between babies following TW or BLW. BLW appears to be socially desirable. Guidance for parents is required, along with larger, longer-term studies, which explore the potential impact of BLW in later childhood.
