The Government should set up mental health teams dealing with babies in every health authority, according to Young Minds.
The charity has outlined its proposals in a policy document called Mental Health in Infancy, which will be distributed to policy makers at national and local level in a bid to persuade them to take action.
The charity says that babies can develop mental health problems if they fail to develop a good relationship with their primary caregiver. But these problems are often misunderstood or left undetected because babies do not exhibit the same types of symptoms as adults.
It warns that if mental health problems in babies are not tackled, they can result in outcomes such as childhood educational problems, crime, teenage pregnancy and substance abuse.
