What is complimentary food? A guide for infant nutrition

4 min read

According to the World Health Organization (WHO), complementary foods are needed when an infant's nutritional requirements exceed what breast milk or formula alone can provide, typically starting around six months of age. This process of introducing solids is commonly, though mistakenly, referred to as complimentary food.

Quick Summary

Complementary food refers to nutrient-rich liquids and solids introduced to infants from about 6 months of age to supplement breast milk or formula. It is a critical period for meeting growing nutritional needs, developing eating skills, and establishing lifelong healthy eating habits.

Key Points

  • Correction: "Complimentary food" is a common error; the correct term is "complementary food", meaning it supplements breast milk or formula.

  • Timing: Introduce complementary foods around six months, when an infant's nutritional needs exceed what milk can provide.

  • Readiness: Look for developmental signs like good head control, interest in food, and ability to swallow purees.

  • Nutrient Focus: Prioritize iron-rich foods, such as fortified cereal and pureed meats, as iron needs increase significantly after six months.

  • Feeding Style: Practice responsive feeding by paying attention to your baby's hunger and fullness cues to build a healthy relationship with food.

  • Safety: Avoid choking hazards, honey for babies under one year, and refrain from adding salt or sugar to foods.

  • Progression: Gradually increase food texture and variety, moving from purees to finger foods as the infant develops.

Demystifying Complementary Food

The term "complimentary food" is a common but incorrect phrasing. The correct and technical term is "complementary food," which means food that complements, or adds to, an infant's diet of breast milk or formula. The World Health Organization (WHO) and other leading health authorities define the complementary feeding period as the time when an infant's nutritional needs can no longer be met by milk alone. This period typically begins at six months of age and continues through 24 months, or beyond.

Why is complementary feeding so important?

After six months, an infant's energy and nutrient needs, particularly for iron and zinc, begin to outpace what breast milk can provide. Appropriate complementary feeding is vital for healthy growth, cognitive development, and preventing malnutrition. It also plays a key role in preventing conditions like stunting and micronutrient deficiencies. Introducing a diverse array of nutritious foods from different food groups also helps to shape a child's food preferences and reduce the risk of non-communicable diseases later in life.

Recognizing Readiness and Introducing First Foods

Introducing complementary foods should be a gradual and responsive process, not a forced one. The best time to start is when your baby shows developmental signs of readiness, not just at a specific age.

Key signs your baby is ready for complementary food

  • Good head and neck control: The baby should be able to sit with minimal support and hold their head steady.
  • Loss of tongue-thrust reflex: They no longer automatically push pureed foods out of their mouth with their tongue.
  • Chewing motions: The baby makes chewing or munching motions.
  • Increased interest in food: They watch others eat and may reach for food.
  • Ability to swallow: They can move pureed food to the back of their mouth and swallow it, rather than just spitting it out.

Examples of nutrient-rich first foods

  • Iron-fortified infant cereal: A classic first food, often mixed with breast milk or formula.
  • Mashed or pureed meat, poultry, or fish: Excellent sources of iron and zinc.
  • Pureed vegetables: Soft-cooked vegetables like sweet potato, pumpkin, and carrots.
  • Pureed fruits: Mashed banana, avocado, and soft cooked apple or pear are good choices.
  • Legumes: Pureed lentils or beans provide protein and iron.
  • Dairy: Full-fat yogurt and cheese can be introduced after six months.

Comparison of feeding approaches

Feature Purees & Spoon-Feeding Baby-Led Weaning (BLW) Combination
Method Caregiver feeds baby pureed or mashed foods from a spoon. Baby self-feeds soft, finger-sized pieces of food. Blends elements of both approaches.
Control Caregiver controls the pace and amount of food offered. Baby controls what and how much they eat from the start. Combines caregiver guidance with self-exploration.
Food Texture Starts with smooth purees, progressing to thicker, lumpy textures. Starts directly with appropriate finger foods; texture-focused. Varies, can offer purees on a spoon and finger foods.
Skill Development Develops swallowing and acceptance of new tastes. Oral motor skills progress more slowly. Promotes fine motor skills, hand-eye coordination, and chewing from the start. Supports a range of skill development; offers a fallback if BLW is challenging.
Mess Factor Generally less messy, especially in early stages. Often very messy, as the baby explores food by touching, squishing, and throwing it. Variable; depends on the balance of purees and finger foods.

Responsive Feeding and Safety Precautions

Responsive feeding is a crucial aspect of introducing complementary foods. It involves watching for and responding to your baby's hunger and fullness cues, allowing them to guide the feeding experience. This respectful approach helps establish a healthy relationship with food and prevents over- or under-feeding.

Safety tips for complementary feeding

  • Supervise meals: Always stay with your baby while they are eating to prevent choking.
  • Avoid choking hazards: Do not offer whole grapes, raw carrots, whole nuts, popcorn, or large chunks of meat. Cut round foods into small, lengthwise pieces.
  • Prevent food poisoning: Store and prepare food hygienically. Ensure all tools and utensils are clean.
  • Be cautious with allergens: The American Academy of Pediatrics now advises introducing common allergenic foods (e.g., eggs, peanuts) early, around six months, to potentially reduce allergy risk, but you should discuss this with your pediatrician first.
  • No added salt or sugar: Avoid adding salt and sugar to baby's food, as their kidneys cannot handle it, and it can promote unhealthy eating habits.
  • Avoid honey before age one: Honey can contain botulism spores, which can be dangerous for infants under 12 months.
  • Limited juice: Fruit juice has little nutritional value compared to whole fruit and can displace more nutrient-rich foods.

The Role of Breast Milk and Conclusion

Throughout the complementary feeding period, breast milk or formula continues to be a vital source of nutrition. The goal is to complement, not replace, these milk feeds. The proportion of a child's nutritional needs met by solids will gradually increase, but milk remains important, with WHO recommending continued breastfeeding up to two years or beyond.

In conclusion, understanding what is complementary food is crucial for a child's health and development. While the term "complimentary food" is often used, the practice of introducing solids at around six months, in addition to milk, is a fundamental step in infant nutrition. Following guidelines for timing, nutrient density, and safety, while adopting a responsive feeding style, ensures a smooth transition to family meals and sets the foundation for a lifetime of healthy eating.

For more detailed guidance, health organizations like the World Health Organization provide extensive resources on complementary feeding.

Complementary feeding timeline and progression

  • 6-8 months: Start with pureed, mashed, or semi-solid foods. Offer 2-3 meals per day, beginning with small amounts. Introduce iron-rich foods first.
  • 8-12 months: Gradually increase the variety of food and move towards lumpy, minced, or finger foods to develop chewing skills. Increase frequency to 3-4 meals per day.
  • 12-24 months: By one year, most children can eat similar foods to the rest of the family, provided they are cut safely. Continue 3-4 meals daily with 1-2 nutritious snacks. Breastfeeding can continue alongside this progression.

Frequently Asked Questions

Complementary food is the correct term and refers to solids and liquids introduced to an infant's diet in addition to breast milk or formula. 'Complimentary food' is a common spelling error; the word 'complimentary' actually means free of charge.

The World Health Organization recommends starting complementary feeding at around 6 months of age. You should also watch for developmental cues, such as good head control and showing an interest in the food you are eating.

Iron-rich foods are recommended as first foods, as a baby's iron stores begin to deplete around 6 months. Good options include iron-fortified infant cereals, pureed meats, and pureed legumes. After this, you can introduce a variety of other pureed or soft foods.

Responsive feeding is an approach where you pay close attention to your baby's hunger and fullness cues. This means feeding them slowly, patiently, and encouraging them to eat, but not forcing them. It helps to develop healthy eating habits.

Honey can contain botulism spores, which can be dangerous for infants under 12 months. An infant's immature digestive system cannot process these spores, which can cause a serious illness.

Recent guidelines suggest that introducing common allergenic foods like eggs and peanuts early (around 6 months) may help reduce the risk of allergies. However, it is essential to consult with your pediatrician for personalized advice, especially if there is a family history of allergies.

You should avoid giving babies choking hazards such as whole nuts, whole grapes, or hard raw vegetables. Also, do not add salt, sugar, or low-nutrient drinks like juice. Unpasteurized products and certain fish should also be avoided.
