The Scottish Government is investing £38.4million in training “named persons” to improve child protection.
A spokeswoman said the money would be spent between 2015-20 to ensure all people aged under 18 and their families had a guardian they could call on in times of need.
Opposition MSPs who backed the policy embodied within the Children’s and Young People (Scotland) Bill had warned that good intentions would be undermined if sufficient resources were not in place.
The legislation will ensure children get more access to nursery provision, free school meals and increased care support.
It has also led to threats of a legal challenge over plans to appoint a “state guardian” for every child.
They would include health workers and head teachers who will be asked to look out for the welfare and wellbeing of everyone up to the age of 18.
The move has won the backing of the charity Children 1st, which said it “strongly supported” the measure. But the Christian Institute pledged to mount a £30,000 challenge to the entire bill.
Anne Houston, chief executive of Children 1st, said appointing a named person would mean parents and children could get additional support and advice when it was needed.
She said: “We know from our long experience of working with and for families that making sure they get the right support at the right time is key to enabling more children to thrive safely in their families.
“It’s been suggested the named person might take rights away from parents.
“Actually, it does the opposite. This legal provision gives parents and children rights to call on professionals when they need advice, info and support.”
Liberal Democrat education spokesman and MSP for Orkney Liam McArthur said last night: “The establishment of a ‘named person’ approach has attracted criticism but is backed by the evidence parliament received and can deliver benefits for children, young people and their parents.”
Labour MSP Neil Bibby said it was still not clear how the named person role would be properly resourced.
North-east Conservative MSP Nanette Milne, who along with her party colleagues abstained in the vote, claimed the policy would “tip the balance of family responsibility away from parents”.
“Forcing young people to have a named person will dilute the resources available for our most vulnerable children,” she said.
“The SNP has told 16-year-olds they are mature enough to vote but not mature enough to go about their business without having a named person.”
