Starting Solids & Baby-Led Weaning Guide

WHO and ESPGHAN clinical guidelines on starting solids: developmental readiness signs, purees vs BLW, allergen introduction, and foods to avoid.

Starting Solids & Baby-Led Weaning Guide
Soft finger foods squishable between thumb and forefinger allow safe exploration of textures.

1. When to Start Solids? (Readiness Signs)

The World Health Organization (WHO) and the European Society for Paediatric Gastroenterology (ESPGHAN) recommend starting solid foods around 6 months of age (not before 17 weeks and not later than 26 weeks). Look for all 4 developmental readiness signs:

  • 1. Sitting with minimal support: Baby can hold their head steady and upright without slumping.
  • 2. Loss of the tongue-thrust reflex: Baby no longer pushes food automatically out of their mouth with their tongue.
  • 3. Coordinated hand-to-mouth movement: Baby can grasp food or toys and accurately bring them to their mouth.
  • 4. Genuine food curiosity: Reaching for food on your plate and intently watching you eat.

2. Traditional Purees vs. Baby-Led Weaning (BLW)

Traditional Purees (Spoon-fed)
Smooth single-ingredient vegetable purees (zucchini, broccoli, cauliflower, carrot) followed by single-grain iron-fortified cereals (buckwheat, oatmeal). Gradually thicken texture by 8–9 months.
Baby-Led Weaning (BLW)
Soft finger foods offered directly from 6 months. Baby self-feeds, developing fine motor skills and chewing control. Foods must be soft enough to squish easily between adult thumb and forefinger.

3. Introducing The Top Allergenic Foods (Modern Guidelines)

Outdated advice suggested delaying allergens. Modern evidence shows that early introduction of common food allergens around 6 months prevents food allergies:

  • Top Allergens: Well-cooked egg, peanut butter (thinned with warm water or puree — never whole peanuts!), cow's milk products (yogurt/cheese), fish, shellfish, soy, wheat (gluten), and tree nuts (nut butters).
  • Rules of Introduction: Introduce one new allergen at a time in the morning on an empty skin day. Offer a tiny amount first, observe for 2 hours, and keep offering regularly 2–3 times a week to maintain tolerance.
🛑 Foods Strictly Prohibited Before 12 Months:
  • HONEY: Never give honey to infants under 1 year due to the risk of infant botulism (spores of Clostridium botulinum produce lethal neurotoxins in the immature infant gut).
  • Whole Nuts & Round Fruits: Whole grapes, cherry tomatoes, and hard candies must be quartered lengthwise to prevent fatal airway obstruction.
  • Added Salt & Sugar: Immature kidneys cannot handle excess sodium, and added sugars promote tooth decay and metabolic imbalance.
  • Unpasteurized Cheeses & Juices: Risk of severe foodborne bacterial infections (Listeria, Salmonella, E. coli).
