At present, most research on BLW is observational, which makes it difficult to draw strong conclusions. Outcomes can be influenced by things like:

• parenting style
• family routines and characteristics
• how closely families follow BLW or traditional weaning guidelines.

It’s also challenging for researchers to measure how these feeding approaches are implemented and to consistently evaluate their long-term outcomes.

Some concerns raised about BLW are often linked to poor adherence to guidelines. These include:

• Choking risk: 

Choking is a risk with any method of introducing solids. Your baby must be developmentally ready before starting. Foods should be prepared safely to reduce choking hazards, and high-risk foods should be avoided until your baby is older.

• Nutritional gaps: 

Because babies self-select what and how much to eat, there’s a risk they may not get enough of key nutrients, particularly iron, zinc and Vitamin B12. While breastmilk still plays a role, it alone won’t meet your baby’s nutritional needs by six months.

• Excess salt or sugar: 

If your baby is eating family meals, be mindful of added salt and sugar. Seasonings or processed foods can contain levels that are unsuitable for infants.

Some families report positive experiences with BLW, such as:

• more shared family mealtimes
• calmer, less stressful feeding routines
• less pressure for breastfeeding mothers around introducing solids.

For some infants, traditional weaning is the safer option. This includes babies who:

• were born prematurely
• have developmental delays
• have neurological conditions.

Always speak with your local doctor, child and family health nurse or paediatrician if you’re unsure about the best feeding approach for your baby.
