A study suggests that bringing weak children into care at earlier stages is more beneficial and minimize the costs associated with unstable and unhappy care experiences later on.
The number of applications for children to be taken into care has risen since November 2008.
As per reports, the child advisory service in England receives 8,524 applications for children to be taken into care in 2009 as compared with 5,968 in 2008.
The surveys found that children with poor health and mental imbalance, who receive care at later stages, do not improve their health in much better way.
Early care makes things better, and can create a stable and nurturing environment for children.
The government said that care system in any state should be seen as a "positive form of family support".
The state can pay nearly £33,000 more per child per year, if they received poor care.
"We must urgently adopt a more pro-active and positive use of care, one where care is used earlier and more effectively so it becomes a means of real cost avoidance," Martin Narey, Barnardo's chief executive said.
