The age at which complementary (supplementary) foods should be given to infants is:

Question

Accepted Answer

The correct option is 4:
The correct answer is **6 months** because this is the age universally recommended for introducing complementary (or supplementary) foods by major international health bodies, such as the World Health Organization (WHO), UNICEF, and leading national pediatric associations. This recommendation is based on scientific evidence which establishes that for the first six months of life, a baby’s nutritional and immunological needs are optimally met by **exclusive breastfeeding**. After the six-month mark, however, breast milk alone begins to fall short of the rapidly increasing energy, protein, and micronutrient demands, particularly for **iron** and **zinc**, required to sustain rapid growth and physical activity. Furthermore, by six months, most infants have achieved the necessary developmental milestones for safe and effective feeding, including the ability to sit with support, good head and neck control, and the extinction of the involuntary tongue-thrust reflex. Therefore, introducing nutrient-dense complementary foods at 6 months perfectly aligns nutritional needs with physical readiness, ensuring the baby maintains optimal growth while continuing to benefit from breast milk.

The incorrect option is 1:
The incorrect option is **12 months** (one year). Delaying the introduction of complementary foods until this age is highly detrimental to the infant’s growth and development. By 12 months, relying solely on breast milk creates a severe and prolonged **energy and nutrient deficit** that is nearly impossible to fully recover from. This significant nutritional gap can lead to **growth faltering**, **stunting**, and serious micronutrient deficiencies, most notably **Iron Deficiency Anemia**, which negatively impacts cognitive development. The infant also misses a crucial window for developing essential oral-motor skills like chewing and biting, which can cause significant feeding difficulties throughout early childhood.

The incorrect option is 2:
The incorrect option is **4 months**. Introducing complementary foods too early, before the infant is six months old, is generally discouraged as it poses several risks without providing a nutritional advantage. A major concern is the immaturity of the infant's gastrointestinal tract and immune system, which increases the likelihood of **diarrheal diseases** and potential **allergic reactions**. Early introduction often results in **breast milk displacement**, where the baby consumes less nutritionally complete breast milk in favor of less-dense, complementary foods, thereby increasing the risk of overall malnutrition. The infant is also not developmentally ready, as the protective tongue-thrust reflex may still be present, increasing the risk of choking.

The incorrect option is 3:
The incorrect option is **10 months**. While waiting until 10 months is not as harmful as waiting until 12 months, it still represents a significant and suboptimal delay in starting complementary feeding. By delaying until 10 months, the baby has already experienced a four-month period of **chronic nutritional inadequacy** since the six-month mark. This prolonged deficit, especially in energy, protein, and vital micronutrients, significantly compromises their growth trajectory during a critical developmental phase. Moreover, waiting this long can lead to greater **food refusal** and difficulty accepting varied textures, as the critical period for exploring different tastes and textures may have passed.
