Starting solids is one of the most exciting (and confusing) milestones in the first year. Between baby-led weaning, traditional spoon-feeding, and the hybrid approach, the options can feel overwhelming.
Here is what the evidence actually says — and how to choose what works for your family.
When to Start
The NHS recommends starting solid foods at around 6 months — not before 17 weeks (4 months). Signs your baby is ready:
- Sits upright with minimal support and holds their head steady
- Shows interest in food — watching you eat, reaching for food
- Has lost the tongue-thrust reflex (no longer automatically pushes food out of the mouth)
Early introduction (before 4 months) is associated with increased risk of digestive issues and is linked to higher obesity risk. There is no benefit to introducing solids before 6 months for healthy, full-term babies.
What Is Baby-Led Weaning?
Baby-led weaning (BLW), developed by UK health visitor Gill Rapley, skips purees entirely. From around 6 months, babies are offered soft finger foods and encouraged to self-feed.
The core idea: babies learn to chew before they learn to swallow, rather than the other way around. By controlling what they put in their mouth, babies develop a better relationship with food and learn hunger and satiety cues naturally.Safe food preparation for BLW
- Strips: soft fruit, cooked vegetables, meat — cut in strips wider than a finger so the baby can grip them
- Spears: avocado, banana, steamed broccoli florets
- Grated or mashed: harder foods like apple and carrot — raw versions are choking hazards
- Avoid: whole grapes, whole cherry tomatoes, large blobs of nut butter, whole nuts, raw hard vegetables
What Are Traditional Purees?
Spoon-fed purees introduce single foods gradually — starting with smooth single-vegetable or fruit purees, then progressing to more complex textures. This has been the standard guidance in the UK and US for decades.
Advantages: easier to track intake, less mess initially, more familiar to many parents, useful if your baby has texture aversiveness.What Does the Research Say?
The BLISS (Baby-Led Introduction to SolidS) trial — the largest randomised controlled trial of BLW — found:
- BLW does not increase choking risk compared to spoon-feeding when foods are prepared correctly
- BLW babies show better self-regulation of appetite
- BLW is associated with lower BMI at 24 months
- Both approaches result in similar nutritional outcomes at 12 months
The NHS no longer distinguishes between approaches — both are acceptable.
The Hybrid Approach
Most families end up combining both. Spoon-feed first yoghurt, porridge, and soups while offering finger foods alongside. This is practical and evidence-supported — there is no reason to be dogmatic about either approach.
Foods to Avoid in the First Year
Regardless of approach, avoid:
- Salt — no added salt under 12 months (kidneys cannot handle it)
- Honey — risk of infant botulism under 12 months
- Cow's milk as a drink — cow's milk can replace formula/breast milk from 12 months, but can be used in cooking from 6 months
- Whole nuts — choking risk; nut butters thinned with water are fine
- Processed foods, sugary snacks, biscuits — delay as long as possible
- Shark, swordfish, marlin — high mercury content
- Undercooked eggs — must be fully cooked until 12 months (lion-stamped eggs are fine soft-cooked)
Iron Is the Priority Nutrient
Breast milk alone does not provide enough iron from 6 months. Prioritise iron-rich first foods:
- Red meat, poultry
- Oily fish (from 6 months — start with once a week)
- Fortified baby cereals
- Lentils, beans, chickpeas
- Dark leafy greens (combined with vitamin C to improve absorption)
What to Expect in the First Weeks
Expect very little food to be swallowed for the first few weeks — this is normal. The first month of solids is about exploration and texture experience. Milk (breast or formula) remains the primary nutrition source until 12 months.
Gagging is normal and different from choking. A gagging baby is working food to the front of the mouth — it looks alarming but is a safety reflex, not a sign something is wrong. Learn infant choking first aid regardless of approach.

Frequently Asked Questions
When should I start introducing solid foods?
The NHS and WHO recommend starting solid foods at around 6 months. Signs of readiness include sitting upright with minimal support, holding their head steady, and showing interest in food. Starting before 17 weeks is not recommended.
Is baby-led weaning safe?
Yes, when done correctly. Research shows baby-led weaning does not increase choking risk compared to spoon-feeding when age-appropriate foods and preparation are used. The key is cutting food safely — strips wider than a finger for soft foods, grated or cooked soft for harder textures.
Do I need to give purees first?
No. The NHS no longer recommends starting with purees before lumpy textures. You can go straight to soft finger foods, purees, or a combination. What matters is texture progression: moving from soft to more varied textures over weeks.
