Well seeing as this is a family that turned a walk in closet into a bedroom and don't even feed their children properly or care about their education, I doubt they would be allowed to adopt. Adopted children also need a lot more patience, support and attention than biological children, you need to be extremely dedicated to looking after them and have the ability to be able to get them outside support where needed and I can't see Sue and Noel doing any of those things. Also, certain things they have done in the past to their children could be a trigger for an adopted child, such as, removing door handles off their bedroom doors and fridge locks on the fridge to stop them helping themselves to food. For a child who might have , in the past, been locked in rooms and denied food, that would be extremely triggering for them, not to mention the lack of privacy the child would be given and no space to themselves.
