The Ultimate Guide: When to Start Weaning (5 Signs Your Baby Is Ready for Solids)
The first bite is a huge milestone! This parenting guide explains the official guidelines and the 5 clear developmental signs—including the loss of the tongue-thrust reflex—that signal your baby is ready for solids.
Introducing your baby to solid foods, often called "weaning" or complementary feeding, is one of the most exciting (and messy!) milestones of the first year. It signals a huge leap in development, transitioning your baby from purely milk-based nutrition to eating alongside the family.
The excitement often comes with anxiety: When is the right time? Is milk still enough? What if they choke?
The official guidance from the World Health Organization (WHO) and the American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for the first six months, followed by the introduction of complementary foods while continuing breastfeeding up to two years or beyond.
However, a calendar date is just a guideline. The most reliable indicator is your baby’s developmental readiness. This guide will walk you through the clear physical and behavioral signs that signal your baby is ready to start this next phase of their culinary journey.

Part 1: Why Developmental Readiness Trumps the Clock
The old advice often stated: "Start solids at four months!" We now know this is too early for most babies. Introducing solids before a baby is developmentally ready can increase the risk of allergies, digestive issues, and nutrient imbalance.
Your baby must achieve key physical milestones before they can safely and effectively eat. These physical signs are designed by nature to prevent choking and ensure the baby can digest the food.
5 Clear Signs Your Baby Is Ready to Start Solids
Do not start solids until your baby exhibits all or most of these signs consistently.
1. Can Sit Up Unassisted or with Minimal Support
This is the most crucial safety factor. Your baby must be able to sit upright in a high chair with good, stable head and neck control.
- Why it matters (YMYL): If your baby slouches or has poor head control, they cannot manage food in their mouth effectively, dramatically increasing the risk of choking.
2. Loss of the Tongue-Thrust Reflex (Extrusion Reflex)
Newborns have a protective reflex called the tongue-thrust reflex: if you place anything solid on their tongue, they automatically push it back out. This reflex is designed to prevent them from swallowing foreign objects and ensures they only suckle milk.
- The Sign: When this reflex is gone (usually around 4–6 months), your baby will accept a small spoonful of purée or food without immediately pushing it out. If they keep pushing the food out, they are not ready.
3. Ability to Hold Food and Bring It to the Mouth
Weaning is a self-feeding process, whether you choose purées or Baby-Led Weaning (BLW). Your baby must be able to coordinate their hands to control the food.
- The Sign: They show good hand-eye coordination. They can pick up a toy, look at it, and deliberately bring it to their mouth.
4. Demonstrates Chewing Motions
Even if your baby has no teeth, they need to be able to move their jaw up and down to mash soft foods.
- The Sign: You will see them opening their mouth when food is presented, moving their tongue side-to-side, and imitating a chewing motion. This shows the development of the necessary mouth muscles for managing texture.
5. Increased Appetite and Interest
Your baby is no longer content with milk alone. While this sign alone shouldn't be the deciding factor, it indicates a metabolic need for more fuel.
- The Sign: They watch you eat intently. They may reach for your food, try to grab your plate, or seem unsatisfied immediately after a full milk feeding.
Part 2: Addressing Common Myths and Confusion
Myth: "Starting Solids Early Will Make the Baby Sleep Through the Night."
Debunked: This is a very common wish, but it’s scientifically false. Waking at night is normal for babies; it is not a hunger problem, but a developmental one related to their immature sleep cycles. Research has shown that starting solids early does not increase the duration of nighttime sleep. Focus on feeding readiness, not sleep.
Myth: "My Baby Needs Solids Because They Are Drinking So Much Milk."
The Reality: The baby is likely going through a growth spurt. At 4 months and 6 months, babies often increase their milk intake dramatically. Increasing milk feedings is exactly what they need during a growth spurt. Solids should not replace milk; they should complement milk. Milk remains the primary source of nutrition for the first year.
Part 3: Getting Started Safely (Parenting Guide)
Once your baby exhibits the signs of readiness, the goal is to keep it fun, safe, and stress-free.
The First Foods
Start with single-ingredient, iron-rich foods, as a baby’s iron stores begin to diminish around 6 months.
- Iron-Rich: Iron-fortified baby cereal mixed with breastmilk/formula, puréed meat (chicken, beef), or puréed tofu/beans.
- Vegetables: Puréed sweet potato, avocado (a fantastic first food), or steamed carrots.
- Rule of 3 Days: Introduce only one new food every three days. This makes it easy to identify any potential allergic reactions or sensitivities.
Safety First: Choking Prevention
Always supervise your baby while they eat.
- Position: The baby must be sitting upright, never reclined.
- Food Size (BLW): If you use Baby-Led Weaning, food should be cut into finger-sized strips that the baby can easily grip (the size of an adult finger) and should be soft enough to be easily mashed between your thumb and forefinger. Avoid small, hard foods (like whole grapes or chunks of raw apple) that are choking hazards.
Your Next Step: Plan Your Weaning Journey
Starting solids is a journey of discovery, not a race. You need a structured approach that respects your baby's unique timeline and provides you with the peace of mind that you are doing it safely and nutritiously.

Frequently Asked Questions (FAQ)
Q: Is it better to start with purées or Baby-Led Weaning (BLW)? A: Both methods are excellent! Purées give you control over texture and nutrients. BLW allows the baby to explore food shape and texture independently. The best method is the one you feel most comfortable with, and you can even combine both (a "combination approach").
Q: My baby is 5 months old and grabs for my food. Should I start? A: No, not yet. Grabbing for food shows interest (Sign #5), but if the baby can't sit up completely on their own (Sign #1) and still has the tongue-thrust reflex (Sign #2), they are not safe. Continue to let them watch you eat, but only offer milk.
Q: How much food should my baby eat when they start? A: Very little! For the first month, solids are mostly for exploration and practice, not calories. Start with 1-2 teaspoons once a day. The main source of calories and nutrition remains breastmilk or formula.
Q: Should I put cereal in my baby's bottle? A: No. The AAP strongly advises against putting solids in a bottle, as it is a choking hazard and has been linked to excessive weight gain. Food should be offered on a spoon or as a finger food when the baby is sitting upright.
