I've just finished watching both episodes on iPlayer.
The couple in last night's seemed very damaged by their own upbringings, they had no ability to look after a baby and i'm glad this one was taken away before he was harmed.
The first episode was a whole different story. Both parents were seriously neglectful, they seemed to care more for the dog than their poor son. The father shouting at the social workers was ridiculous when in one scene he had the little boy in an arm lock. I'm glad the mum decided to have both children adopted out, it was the best thing for all concerned.
