The Government needs to help poor parents by developing a "substantive family policy", a new report claims.
In a new study from Demos on the self-esteem of teenage girls, researchers highlighted the importance of the mother-daughter relationship.
The report, which will be published later this month, will argue that the Government needs to do more to deliver on a "substantive family policy" to build on this potential.
Julia Margo, deputy director of Demos, said: "The relationship between mother and daughter is crucial.
"Supporting parents, especially from lower socio-economic groups, should be a central part of the Government's youth policy.
"But instead, the growth agenda presents 'family friendly' policies as getting in the way of enterprise and Britain's future prosperity."
According to the poll of more than 500 women aged between 16 and 19, mothers are still the first port of call for teenage girls looking for advice on health, school, college or work.
The study showed that 40% of teenage girls are most likely to turn to their mothers for advice about their health, with only 18% opting to go to their doctor.
But mums are still kept in the dark when it comes to relationships, with more than half of teenage girls turning to their best friend (53%) and just one in 10 turning to their mother (11%).
