I am gratified to see that a study, commissioned by Nanny herself, has proven what I have been saying many times; namely that the state should not be rearing children, parents should.
Nanny's study (performed by the University of Oxford and the Institute for Fiscal Studies) evaluated Nanny's £370M Neighbourhood Nurseries Scheme. The research found that toddlers, who went to these places full time, were likely to become "anti social", bossy and selfish.
As I have often stated, like it or not, the best people to rear children are the parents not the state.
Mankind has done pretty well over the past 150,000 years or so, by following the natural order of parental rearing. When the state tries to replace the parents you get hideous consequences, eg Nazi Germany.
Nanny should keep her beak out of the family.
