A new study from British researchers published this week in JAMA Pediatrics supports what caregivers have thought for generations - that some solids in an infant's diet may result in a little more rest for parents.
They also found that families in the standard introduction group were more likely than those in the early introduction group to report a small problem (OR 1.2, 95% CI 1.05-1.41) or a very serious problem (OR 1.8, 95% CI 1.22-2.61) with their child's sleep.
The researchers' findings were limited to babies' sleep duration, not on what is nutritionally best for babies.
The NHS Choices website says: "Starting solid food won't make your baby any more likely to sleep through the night".
Co author of the study Dr Michael Perkin, from St George's, University of London, said: "Given that infant sleep directly affects parental quality of life, even a small improvement can have important benefits".
Parents have been told for years to delay introducing solid food, mainly to encourage mothers to continue breastfeeding for as long as possible, but also because scientists thought food introduced earlier could lead to allergies.
Professor Mary Fewtrell of the Royal College of Paediatrics and Child Health said: 'These are interesting findings from a large randomised controlled trial.
"We expect to see updated recommendations on infant feeding in the not too distant future".
First foods can include mashed or soft cooked fruits and vegetables such as apple, pear and potato, sweet potato or parsnips.
Despite the official piece of advice, about 75% of mothers gave solid food to their babies before five months - 26% of the babies were waking up at night frequently because of this reason.
