The sheer physical effort involved in breastfeeding may leave babies with stronger lungs well into childhood, researchers suggest.
A study of 10-year-olds on the Isle of Wight by UK and US scientists found much better lung function in those breastfed for at least four months.
The different mechanics and duration of sucking may be partly responsible, they said, in the journal Thorax.
If so, changes to the design of bottles could mimic this effect.
Studies have established that breastfeeding protects babies from respiratory problems early in life, but the relationship with lung power later in childhood is less clear-cut. More...
