Baby Led Weaning vs Purees: Which is Right for Your Baby?

When it comes to starting solids, parents today face a choice that didn't really exist a generation ago: the traditional spoon-fed purée approach, or the increasingly popular baby led weaning (BLW). Here's an honest look at both — including what the evidence actually says.

What is baby led weaning?

Baby led weaning (a term coined by UK health visitor Gill Rapley in the 2000s) means offering babies soft finger foods from the start of weaning and letting them self-feed entirely, with no purees and no spoon-feeding.

The philosophy: babies are allowed to explore, touch, taste, and chew food at their own pace. They're in control of what goes in their mouth and how much.

What BLW looks like in practice:

• Baby sits in a high chair at family meals
• You offer soft strips or pieces of food from around 6 months
• Baby explores food with their hands, gums, and eventually teeth
• Some food goes in, lots goes on the floor, considerable amounts go on baby
• No smooth purees; no spoon

What is traditional/spoon-led weaning?

Traditional weaning starts with smooth purees — single vegetable purees, then combined flavours — gradually progressing to mashed textures, then soft lumps, and eventually finger foods. The caregiver controls the spoon and the pace.

What does the evidence say?

Both approaches produce healthy, well-nourished babies when done correctly. But there are some interesting differences:

Food acceptance and fussiness

BLW appears to reduce fussiness and food neophobia (fear of new foods) in toddlers. Research suggests self-feeding babies are more comfortable with a variety of textures and flavours. However, the evidence isn't definitive.

Iron intake

This is the BLW concern most often raised by dietitians. Iron is critical in the 6–12 month period (breast milk iron decreases and babies' stores deplete). Iron-rich foods (meat, pulses, fortified cereals) need to be actively offered in a BLW approach — they won't magically appear. BLW families need to be deliberate about including iron-rich finger foods from the start.

Choking risk

This is the most common BLW concern. Research suggests that gagging (normal and safe) is common in BLW; choking (airway obstruction — an emergency) is not significantly more common than in traditional weaning when appropriate foods are offered. Key distinction: gagging is protective and normal; choking is rare in both approaches.

Before starting BLW especially, take an infant first aid course covering choking response — St John Ambulance offers free online guidance.

Obesity

Some studies suggest BLW babies may have slightly lower BMI in early childhood — theorised to be because they self-regulate intake more naturally. Evidence is limited.

Parental anxiety

Multiple studies show parents doing BLW report significantly higher anxiety than those doing purees, particularly around gagging. If gagging reduces you to a pile of anxiety at every meal, BLW may not be the right primary approach.

The case for combining both

The honest truth is that the majority of UK families combine both approaches — and this is arguably the best of both worlds:

• Purees allow you to get good quantities of iron-rich foods in reliably
• Finger foods develop self-feeding skills and texture tolerance
• You can follow baby's lead more fully as confidence grows

A combination approach might look like: spoon-fed breakfast (iron-fortified porridge), finger food lunch (soft broccoli, strips of omelette), spoon-fed dinner with some finger food alongside.

What BLW requires

If you want to go fully BLW, make sure you have:

• A baby who can sit independently with good head control — this is a safety requirement, not optional
• Correct food preparation: Soft enough to squash between your finger and thumb. Long strips or spears (not small pieces or rounds that could cause choking). Grated cheese, squashed peas, soft banana, cooked carrot spears, strips of chicken, broccoli florets with a long stalk.
• High chair with a footrest — baby needs stability to manage self-feeding
• Iron-rich foods at every meal
• Tolerance for mess — it is extraordinary

What traditional weaning requires

• Age-appropriate textures — smooth at first, then textured
• Progression from single ingredients to mixed
• Move toward finger foods by 8–9 months to develop self-feeding
• Avoid over-relying on pouches — spoon-feeding from a pouch doesn't support texture progression

First foods for both approaches

BLW finger foods:

• Soft cooked broccoli florets
• Avocado strips
• Banana chunks
• Strips of scrambled egg
• Soft cooked carrot spears
• Strips of toast with nut butter

Puree first foods:

• Sweet potato puree
• Butternut squash puree
• Parsnip puree
• Courgette puree
• Baby rice or porridge

Introduce new foods 2–3 days apart to spot reactions. Introduce the top allergens (peanut, egg, tree nuts, wheat, fish, dairy) early and one at a time.
