When should complementary foods be introduced according to infant nutrition guidelines?

The introduction of complementary foods is recommended to begin at 4 to 6 months of age, as this is the period when infants typically demonstrate readiness for solids. At around this age, most infants have developed the necessary skills such as head and neck control, the ability to sit up with support, and diminished tongue thrust reflex, which allows them to accept food other than breast milk or formula.

This stage is crucial because infants' nutritional needs begin to outpace what breast milk or formula alone can provide. By introducing complementary foods during this timeframe, caregivers can help ensure that the child receives essential nutrients that support growth and development, including iron and zinc.

Introducing solids too early, such as at 2 months, may pose risks including difficulty with digestion and potential allergic reactions. Similarly, waiting too long, such as starting at 8 or 10 months, may delay important sensory and motor development opportunities and increase the risk of picky eating habits later on. Thus, beginning complementary foods between 4 and 6 months aligns with both developmental readiness and nutritional needs for infants.
