Results from a recent study of 10-year-olds on the Isle of Wight by Brtish and US scientists found much better lung function in babies that were breastfed for at least four months.
A total of 1,456 babies were followed all the way through to their 10th year to test this.

The different mechanics and duration of sucking may be partly responsible according to a recent article in the Journal, Thorax.
