Raising Healthy Eaters - When is the Baby Ready for Solid Food?

Waiting until about six months to introduce solid foods is crucial for ensuring that your baby’s digestive system and nutritional needs are adequately met.

• Breastmilk contains 50+ known immune factors, and also facilitates the development of “good bacteria” that protect baby’s gut. 
• Exclusive breastfeeding for at least 3-4 months (compared to non-exclusive breastfeeding) further decreases the risk of respiratory tract infections, ear infections, necrotizing enterocolitis (NEC), sudden infant death syndrome (SIDS), allergic disease, celiac disease, and type 1 diabetes.  
• Exclusive breastfeeding for 6 months (compared to 4-6 months), further decreases the risk of gastrointestinal infection and respiratory infection. (AAP 2012, Naylor & Morrow  2001)

2. Baby’s digestive system will have time to mature

If solids are started before a baby’s system is ready to handle them, they are poorly digested and may cause unpleasant reactions (digestive upset, gas, constipation, etc.). Digestion of fats, protein, and complex carbohydrates is incomplete in infancy, but human milk contains enzymes that aid efficient digestion (Naylor & Morrow  2001).

• In addition, from birth until somewhere between four and six months of age babies possess what is often referred to as an “open gut.” This means that the spaces between the cells of the small intestines will readily allow intact macromolecules, including whole proteins and pathogens, to pass directly into the bloodstream.
• This is great for your breastfed baby as it allows beneficial antibodies in breastmilk to pass more directly into baby’s bloodstream, but it also means that large proteins from other foods (which may predispose baby to allergies) and disease-causing pathogens can pass right through, too. 
• During baby’s first 4-6 months, while the gut is still “open,” antibodies (sIgA) from breastmilk coat baby’s digestive tract and provide passiveimmunity, reducing the likelihood of illness and allergic reactions before gut closure occurs.
• Baby starts producing these antibodies on his own at around 6 months, and gut closure should have occurred by this time also. 

3. Baby will be developmentally ready to eat foods that are not liquids.. 

• A review done by Naylor & Morrow (2001)concluded, “These clinical reports indicate that the majority of normal full term infants are not developmentally ready for the transition from suckling to sucking or for managing semi-solids and solid foods in addition to liquids until between six and eight months of age.”

4.Baby will have a lower risk of obesity in the future.

• The early introduction of solids in infancy is associated with increased body fat and weight in adolescents and adults. (AAP 2012, Wilson 1998, von Kries 1999, Kalies 2005)

5.Starting solids will be easier.

• Babies who start solids later can feed themselves.

6. Baby may have more protection from iron-deficiency anemia.

• The introduction of iron supplements and iron-fortified foods, particularly during the first six months, reduces the efficiency of baby’s iron absorption.
• In one study of healthy, full-term infants (Pisacane, 1995), the researchers concluded that babies who were exclusively breastfed for 7 months (and were not give iron supplements or iron-fortified cereals) had significantly higher hemoglobin levels at one year than breastfed babies who received solid foods earlier than seven months.
• The researchers found nocases of anemia within the first year in babies breastfed exclusively for seven months and concluded that breastfeeding exclusively for seven months reduces the risk of anemia.

7.Mom will more easily maintain her milk supply.

• Studies have shown that for babies under six months, solids tend to replacebreastmilk in a baby’s diet – they do not add to baby’s total intake (WHO 2003, Cohen 1994, Dewey 1999).
• The more solids that baby eats, the less milk he takes from mom, and less milk taken from mom means less milk production. Babies who eat lots of solids or who start solids early tend to wean prematurely.

Overall, waiting until six months ensures a smoother transition to solids and supports your baby’s healthy growth and development.
