Sadly, the amount of help you receive seems to depend largely on the agency you are with. And they can't really chaneg that now!
There is also much less help for emotional/behavioural probelsm and/or mental health problems than there is with physical or learning difficulties. ( I know, i can hear a hollow laugh from the parenst of SN kids )
For example, in some areas the child psychiatic service won't even take referrals for children with "conduct disorders" or attachment disorder and they wont even acknowledge personality disorders in children. Most mental illnesses are very underdiagnosed eg bi-polar or depression as they can manifest differently in children
The standard assumption in child therapy/psychaitry is that its not the child who has the problem, its the family and the child is simpy acting it out. So they often wont work with adoptive families as they are by definintion, the souce of the problem. It doesnt matter that the child has a horrendous past and an family history of such problems.
TBH I think its always harder to get help for problems that are invisible. Kids in wheelchairs get ( usually) public sympathy. Kids with ASD having tantrums in Asda get dirty looks.
Once these kids are adopted Ss can wash their hands of them. In theory they cant but they often do. they will say they are so stretched that they can only take on cases where there are SERIOUS child protection issues. So if a parent threatens a child with a knife,they will help. If a teenager threatens their adoptive mother with a knife they will do nothing. At best they will allocate them a worker who will take them out to macdaonald, chat to them and tell the parents " he seems all right to me . tell me are you having problems in your marraige?"
If the kids act up in school, they are less likely to get excluded if they are fostered, as SS will put pressure on the school not to exclude them.
anyway, i really hope that I am totally over reacting and its just normal teenage behaviour
