Complementary Feeding Guide: Starting Solids at 6 Months

Watching your baby grow from a milk-only newborn to someone who eyes your plate with curiosity is one of the more exciting milestones of early parenthood. Complementary feeding, the gradual introduction of foods alongside breast milk or formula, marks a turning point in your baby's nutrition and development. Getting it right matters: start too early, and your baby's gut may not be ready; start too late, and you risk nutritional gaps, particularly in iron. This guide walks you through everything, from reading readiness cues to building a practical feeding schedule.

Complementary feeding means giving a baby foods and liquids other than breast milk or infant formula, while continuing to offer milk. The word "complementary" is deliberate: solids add to milk feeds; they do not replace them, at least not in the early months.

The World Health Organisation recommends exclusive breastfeeding for the first 6 months of life, after which complementary feeding should begin while breastfeeding continues up to 2 years or beyond. No single food, including breast milk, meets every nutritional need indefinitely as a baby grows. The gap must be filled gradually and safely.

Most babies are developmentally ready for complementary feeding at around 6 months. Starting before 4 months is not recommended; before that, the swallowing reflex and gut lining are not mature enough for safe solid intake.

Look for these readiness signs rather than relying on age alone:

• The baby can hold their head steady and sit upright with minimal support.
• They show clear interest in food, watching others eat, reaching toward plates, or opening their mouth when food approaches.
• The tongue-thrust reflex has faded. Early on, babies automatically push objects out with their tongue; when this weakens, they can move food toward the back of the mouth and swallow.
• They have roughly doubled their birth weight, which usually happens by around 6 months.

If you are unsure whether your baby is ready, your paediatrician can assess developmental milestones at the 6-month well-baby visit. As you settle into this new routine, you may also find it helpful to revisit newborn care essentials for new parents for guidance on other early developmental milestones.

Good First Foods

The priority at 6 months is iron, because breast milk alone no longer supplies enough for a rapidly growing baby. Strong starting options include:

• Iron-rich purees such as mashed or pureed meats (chicken, fish) and cooked, mashed lentils or dal.
• Fortified infant cereals, single-grain rice or oat varieties mixed to a thin, smooth consistency.
• Soft mashed vegetables such as sweet potato, carrot, pumpkin, and peas all work well.
• Mashed fruits like ripe banana, cooked apple, and pear are easy first choices.

Offer one food at a time so you can identify any reactions. Textures should be smooth purees at first, progressing to thicker mashes and soft lumps over the following weeks.

Introducing Common Allergens

Current evidence suggests that delaying allergenic foods such as peanut, egg, fish, and wheat does not reduce allergy risk and may actually increase it. Introduce them one at a time during the day, when you can observe your baby for several hours afterwards. Always speak with your paediatrician first if there is a family history of food allergy or if your baby has eczema.

Starting solids can feel daunting, but a simple structure makes it manageable.

1. Choose the right moment. Offer solids when your baby is alert and neither starving nor full. Mid-morning, after a short milk feed, often works well.
2. Start small. One to two teaspoons is plenty for the first few days. The goal at this stage is exposure, not nutrition.
3. One new food at a time. Introduce a single ingredient and wait three days before adding the next. This is the 3-day rule, and it makes it straightforward to identify the cause if a reaction occurs.
4. Watch for reactions. Mild fussiness is normal. Stop feeding and contact your doctor if you notice a rash, vomiting, swelling, or any difficulty breathing.
5. Progress textures gradually. Move from smooth purees toward mashed, then soft lumps, and finally soft finger foods by around 8 to 9 months.
6. Let your baby lead the pace. Never force feed. Turning away, clamping the mouth shut, or crying are clear cues to stop for that meal.

At 6 months, a typical serving is 2 to 3 teaspoons per meal. By 9 months, many babies comfortably manage 3 to 4 tablespoons per meal, two to three times a day.

The table below is a guide, not a rigid rule. Milk remains the main source of nutrition throughout this entire period.

Do not reduce milk feeds too quickly. Most of a baby's calories still come from breast milk or formula until close to 9 to 12 months.

Some foods carry genuine risks for babies under 12 months and should be left out entirely:

• Honey carries a risk of infant botulism, a rare but serious illness caused by bacterial spores. Avoid it until after the first birthday.
• Cow's milk is not suitable as a primary drink before 12 months, though small amounts used in cooking, such as in a sauce or porridge, are fine.
• Added salt and sugar should be avoided. Infant kidneys cannot handle added salt, and sugar promotes poor taste preferences and early tooth decay.
• Hard, round, or sticky foods, including whole grapes, whole nuts, raw carrot sticks, large apple chunks, and large spoonfuls of nut butter,r are choking hazards. Cut everything small and keep textures soft.
• Unpasteurized foods such as certain soft cheeses and raw juices carry bacterial risks not suitable for an infant's immune system.

Starting complementary feeding at six months marks an important developmental step that provides necessary nutrients—particularly iron—while allowing your baby to explore new textures and flavours alongside breast milk or formula. By watching for clear readiness cues, offering single-ingredient purees, and following the 3-day rule for new foods, you can safely guide your infant through this transition. Always avoid unsafe items like honey, cow's milk as a primary drink, added salt or sugar, and choking hazards during the first year. If your baby displays persistent mealtime distress, delayed readiness cues, or signs of an allergic reaction, consult your paediatrician promptly.
