looking for a TV programme

Hi All.

A while ago (maybe 2 or 3 years ago... somewhere around there) I saw a documentary about mothers who had trouble bonding with their babies. I can't remember if it was part of a wider-based series, but the topic of bonding/post natal depression was standalone, I think. I remember it covered a particular mum who travelled down (to London?) to see a psychologist who worked with her on gaining a connection with her child. Initially, the child wouldn't keep eye contact with the mother, but would smile at the psychologist. The mother realised her lack of connection was based on problems previous to motherhood. It was a really sensitively put together programme. The psychologist was a woman with short, blond hair... I think.... in case that jogs anyone's memory. 

Long shot, I know, but does this ring any bells with anyone? I'm trying to track down the programme. Thanks.
