Family hubs offering parenting support and youth services will be rolled out across every local authority in England, the government has announced.
The £500 million plan aims to support 500,000 more children in the most disadvantaged areas.
Education Secretary Bridget Phillipson said the "Best Start" family hubs would "give a lifeline" to families.
The Conservatives said there was "little clarity on what's genuinely new and what simply rebrands existing services".
