I know a couple with learning difficultieswho have 3 children.
They are a committed couple and have been together for a long time. When the first child was born, they really struggled. They have no help from child services etc and in the end their son was taken into care.
There was a long legal case. At the end the judge ruled that the local authority have a duty to support and help the parents, but also that their son, who has quite severe autism, should remain in with the foster carers, (lots of reasons) the judge was very clear though that this was a failing of the local authority to suport and care for the parents.
When they got pregnant with their second child, 5 years later, the local authority helped to put a lot of support in place, eg a mother and child placement for the first 2 months, and then daily visits from a support team to help them parent.
They have just had child no.2, and similar has happened again.
I am telling you all this becuase you made need to fight for your right to keep your child and bring them up yourself.
I should also say that all 3 children from this couple have some kind of disability, so need more care than an avergae child.
