Health authorities like the World Health Organization (WHO). The American Academy of Pediatrics and the Australian Health and Medical Research Council (NHMRC) recommend exclusive breastfeeding or formula feeding from birth until around six months of age. This means your baby gets all their nutrition from breast milk or formula during this time—no other liquids or solid foods needed, not even water. When the time comes for starting solids, it’s essential to know the best practices for a smooth transition.

As your little one approaches six months and begins showing signs of readiness, it marks an exciting milestone in their development! While the Australian Infant Feeding Guidelines suggest starting solids around six months, they acknowledge some babies may show readiness between four and six months.

Finding the Sweet Spot: Why Timing Matters When Starting Solids

Why Not Too Early? (Before Four Months)

Starting solids before your baby is truly ready can present several challenges:

• Developing Digestive System: Your baby’s gut is still maturing and may not be able to process solid foods properly.
• Potential Weight Concerns: Some research suggests early introduction might be linked to childhood weight issues, though the evidence is still evolving.
• Safety First: Younger babies are still developing the coordination needed to swallow safely, which could increase choking risks when starting solids too soon.
• Immune System Development: A baby’s immune system is still strengthening, and early introduction might increase the risk of digestive upsets.

Why Not Too Late? (After Six Months)

Delaying starting solids too long also comes with considerations:

• Growing Nutritional Needs: By six months, your baby needs more nutrients than breast milk or formula alone can provide.
• Important Minerals: Iron and zinc stores from birth begin depleting, making starting solids essential for development.
• Learning Window: There appears to be a special period between 4-9 months when babies are most open to accepting different food textures, potentially reducing picky eating later. Introducing solids at the right time helps ensure smoother acceptance of a variety of foods.

Signs Your Baby Is Ready for Starting Solids

One of the most wonderful parts of this journey is watching your unique baby show you when they’re ready! Look for these important signs before starting solids:

• Strong and Steady: Your baby can hold their head up confidently without wobbling.
• Sitting Skills: They can sit with minimal support, creating correct postural alignment for eating solid foods.
• Tongue Control: The natural tongue-thrust reflex (which pushes food out) is diminishing—an essential part of successful feeding when starting solids.
• Hand-to-Mouth Coordination: Bringing hands to their mouth intentionally is a crucial skill for self-feeding.
• Mealtime Curiosity: You might notice your little one watching you eat with genuine interest or reaching toward your plate—showing cognitive readiness for starting solids.

These developmental milestones show that your baby has developed the physical abilities and interest needed for a positive experience with solid foods. Responding to these cues—rather than just following a calendar—helps create a trusting, enjoyable relationship with food from the very beginning of starting solids.

The In-Between Time: Four to Six Months

Many parents notice their babies showing interest in food around four months, but interest alone doesn’t necessarily mean it’s time for starting solids. It’s easy to misinterpret normal developmental behaviors—like increased milk appetite during growth spurts, changing sleep patterns, or natural curiosity—as signs of readiness.

Around four months, many babies experience what’s commonly called the “four-month sleep regression,” which is actually a period of incredible brain development that can make babies seem hungrier or fussier than usual. However, this doesn’t always mean they need solid food just yet.

Preparing for Starting Solids Without Rushing

While waiting for true readiness, you can help your baby prepare for starting solids in these meaningful ways:

• Mealtime Inclusion: Let your baby join family meals on your lap, absorbing the social aspects of eating together.
• Gentle Exploration: Offer safe utensils like silicone spoons to explore with their hands and mouth before starting solids. Silicone spoons have fantastic resistive forces to help your little one map their mouth.
• Be Their Guide: Let them watch you eat, demonstrating chewing and enjoying foods. Monkey see, monkey do.
• Behind-the-Scenes Access: Involve them in food preparation when possible. Seeing, smelling, and hearing cooking can build positive food associations before starting solids.
• Building Strength: Practice supported sitting to strengthen the core muscles needed for independent eating when starting solids.

Starting Solids: A Journey Together, Not a Race

Remember that starting solids is a gradual process of discovery for both you and your baby. There’s no rush, no competition, and no single “right way” for starting solids that works for every family. By following your baby’s unique cues and developmental timeline, you create a foundation of trust and enjoyment around food that can last a lifetime.

When the time feels right for both of you, this new adventure of starting solids will unfold naturally—creating not just nutritious meals, but precious memories and positive relationships with food.

Approaches to Starting Solids

When beginning your journey of starting solids, you’ll hear about different approaches:

• Traditional Spoon-Feeding: Introducing smooth purées and gradually increasing texture.
• Baby-Led Weaning: Offering finger foods and allowing baby to self-feed from the beginning.
• Combination Approach: Combining elements of both methods when starting solids.

Whichever method you choose for starting solids, ensuring your baby’s safety and following their cues remains most important. Many families find that a flexible approach to starting solids works best, adapting to their baby’s preferences, development, and family meals.
