When should I introduce allergenic foods like eggs and peanuts?

Current guidelines recommend introducing allergens (egg, peanut, cow's milk in preparations, fish, wheat) starting at 6 months, during the window of immune tolerance. Early introduction, not delayed introduction, reduces the risk of food allergies. Introduce one allergen at a time in small amounts and wait 3 days before the next.

How many meals per day for a 6, 9, and 12-month-old baby?

At 6 months: 2 complementary meals per day (lunch + dinner/snack) plus breastfeeding on demand. At 9 months: 3 meals + 1 snack + breastfeeding. At 12 months: 3 main meals + 2 snacks + breastfeeding. Breast milk or formula remains the primary nutrition source until age 1.

Baby Food Introduction: BLW vs Traditional

Your baby is approaching 6 months and you are facing an avalanche of information — BLW, purees, allergens, forbidden foods, honey, salt, peanuts... Take a breath. In this guide, you will learn exactly what to do, month by month, based on the latest guidelines from the Brazilian Society of Pediatrics (SBP), WHO, and the AAP. No guesswork, no fads — just what works. If you are an expat family in Sao Paulo, understanding the Brazilian healthcare system will help you navigate this journey with confidence.

When to Start Baby Food Introduction

The recommendation from the Brazilian Society of Pediatrics (SBP), the WHO, and the American Academy of Pediatrics is unanimous: start at 6 completed months, while continuing breastfeeding. Before this age, the digestive and immune systems are not mature enough. Your 4-month checkup is when your pediatrician will begin preparing you for this milestone.

Why Not Before 6 Months?

• The baby's gut is more permeable, increasing risk of allergy and infection
• The kidneys cannot yet filter excess salt and minerals
• The tongue-thrust reflex (pushing food out) is still strong
• Breast milk or formula supplies 100% of nutritional needs until 6 months
• Early introduction increases the risk of obesity and chronic diseases later in life

Readiness Signs (Beyond Age)

Age is necessary but not sufficient. Confirm that your baby shows all of these signs:

•Holds head and trunk steady: sits with support without toppling sideways
•Shows interest in food: watches when you eat, opens mouth, tries to grab from your hand
•Lost the tongue-thrust reflex: no longer automatically pushes everything that touches the tongue outward
•Brings objects to mouth: demonstrates adequate hand-to-mouth coordination

Watch Out for False Readiness Signs

Waking more at night, sucking fists, and nursing more frequently are NOT signs that the baby wants food — they are normal developmental behaviors. Do not start food introduction before 6 months for these reasons.

BLW vs Purees vs Participatory Feeding

One of the biggest decisions parents face. Here is the truth: all three approaches are scientifically valid, and you can combine them.

BLW (Baby-Led Weaning)

Baby self-feeds with finger foods from the start.

Pros: Promotes autonomy, develops fine motor skills, exposes baby to different textures.

Cons: More mess, concerns about choking (though studies show no increased risk when done correctly).

Traditional Purees

Mashed foods offered on a spoon by the caregiver.

Pros: Easier to measure intake, familiar to caregivers, good for daycare settings.

Cons: Must evolve texture quickly — do not keep blending beyond 8-9 months.

Participatory (BLISS)

Combines both: baby participates actively but receives support.

Pros: Best of both worlds — baby explores while caregiver ensures iron-rich foods are consumed.

Cons: Requires more planning to balance both approaches.

Pediatrician's Recommendation

I recommend the participatory approach for most families, especially expat families adapting to Brazilian ingredients and food culture. It gives the baby autonomy while ensuring adequate iron and nutrient intake. Whatever method you choose, the key is to never force-feed— respect your baby's hunger and fullness cues.

Month-by-Month Schedule: 6 to 12 Months

6 Months — The Beginning

Meals: 1-2 complementary meals per day (lunch, then add afternoon fruit)

Textures: Mashed with a fork (not blended), soft finger foods for BLW

Priority foods: Iron-rich foods from day one — meat (beef, chicken), beans, lentils, egg yolk

Portion size: Start with 2-3 tablespoons and let baby guide how much they eat

Breast milk or formula remains the main source of nutrition. Offer food AFTER nursing, not instead of it.

7-8 Months — Expanding the Menu

Meals: 2-3 complementary meals per day + 1 fruit snack

Textures: Progressively lumpier — small soft pieces, shredded meat, soft finger foods

New foods: Fish, whole egg, variety of fruits and vegetables, grains

Allergens: Begin introducing common allergens one at a time — egg, peanut (as paste or powder in food), wheat, fish

Water: Start offering small amounts of filtered water in an open cup during meals

9-12 Months — Family Food

Meals: 3 main meals + 2 snacks per day + breastfeeding

Textures: Same food as the family (cut appropriately, without added salt or sugar)

Self-feeding: Encourage using hands, introduce spoon — messiness is part of learning

Social eating: Eat together as a family whenever possible — babies learn by watching

Foods Forbidden Before Age 1

Never Give These to Babies Under 12 Months

×Honey — risk of infant botulism (potentially fatal)
×Salt — overloads immature kidneys
×Sugar — increases obesity risk, creates sweet preference

×Cow's milk as a drink — low iron, high protein load
×Ultra-processed foods — chips, cookies, soda, juice boxes
×Whole nuts and grapes — choking hazard (offer crushed or cut)

Allergen Introduction: The New Evidence

This is one of the areas where recommendations have changed dramatically. Current evidence is clear: early introduction of common allergens (from 6 months) reduces the risk of food allergies. Do not delay introducing eggs, peanuts, fish, wheat, or dairy in cooking.

How to Introduce Allergens Safely

• Introduce one new allergen at a time, in small amounts
• Wait 3 days before introducing the next allergen to monitor for reactions
• Offer in the morning (so you can observe throughout the day)
• Once tolerated, continue offering regularly — consistency maintains tolerance
• If your baby has severe eczema, discuss allergen introduction with your pediatrician first

Gagging vs Choking: Know the Difference

Gagging (Normal)

• Baby coughs, makes faces, may spit food out
• It is NOISY — baby continues breathing
• Face may turn red briefly
• A normal protective reflex — do not intervene
• More common in BLW but happens with purees too

Choking (Emergency)

• Baby is SILENT — cannot cough or cry
• Face turns blue or pale
• Cannot breathe
• Apply first aid maneuvers immediately
• Call emergency services (SAMU 192 in Brazil, or your building's emergency number)

Important for Expat Families

In Brazil, the emergency number for medical emergencies is SAMU 192. Many private hospitals in Sao Paulo also have 24-hour pediatric emergency rooms. Take a first aid course that covers infant choking — many hospitals like Albert Einstein and Sirio-Libanes offer classes in English. Discuss emergency protocols with your pediatrician during your first appointment.

Tips for Expat Families in Brazil

Embrace local ingredients: Brazil has an incredible variety of fruits (manga, mamao, abacate, goiaba), legumes (feijao, lentilha), and grains that are perfect for baby food introduction. Your pediatrician can guide you on local options.

Nutritional guidance is included in well-child visits — you do not need a separate nutritionist for standard food introduction.

Communicate with caregivers: If you have a nanny or babysitter, make sure they understand your feeding approach (BLW vs purees, no salt/sugar/honey). Your pediatrician can provide written guidelines in Portuguese.

Daycare coordination: Brazilian daycares typically follow specific meal schedules. Ask about their feeding practices and share your pediatrician's recommendations.

Frequently Asked Questions

At what age should I start baby food introduction?

At 6 completed months, as recommended by the SBP, WHO, and AAP. The baby must also show readiness signs: head control, interest in food, loss of tongue-thrust reflex, and hand-to-mouth coordination.

What is the difference between BLW, purees, and participatory feeding?

In BLW, the baby self-feeds with finger foods. In purees, foods are mashed and spoon-fed. Participatory feeding (BLISS)combines both. All are validated by pediatric societies and can be mixed based on your family's needs.

Can I give salt, sugar, or honey before age 1?

No. Salt and sugar are prohibited until age 2. Honey is forbidden until age 1 due to the risk of infant botulism, which can be fatal. Never add honey even in small amounts.

When should I introduce allergens like eggs and peanuts?

Current guidelines recommend introducing allergens starting at 6 months, during the window of immune tolerance. Early introduction reduces allergy risk. Introduce one at a time, wait 3 days before the next.

What if my baby chokes during food introduction?

Distinguish gagging (noisy, normal reflex) from choking (silent, baby cannot breathe). Gagging is normal and requires no intervention. For choking, apply first aid maneuvers and call SAMU 192 immediately.

How many meals per day for a 6, 9, and 12-month-old?

At 6 months: 2 complementary meals + breastfeeding. At 9 months: 3 meals + 1 snack + breastfeeding. At 12 months: 3 meals + 2 snacks + breastfeeding. Breast milk or formula remains the primary nutrition source until age 1.
