Quote:
| The prevalence of breastfeeding varied from 45 per cent to 85 per cent, but was not dependent on household income, expenditure on food, number of siblings, birth order, or parental social class in childhood. But those who had been breastfed as babies were 41 per cent more likely to move up the social class hierarchy as adults than those who had been bottle fed. The longer a child was breastfed, the greater were their chances of upward mobility, the results showed. |
