I've just watched this, I can really relate to Zoe's mum.
A lot of peope eg the Times reviewer says why watch this? But I think, as the mum as a SN child, these people aren 't freaks! they have just been dealt certain cards ... in most cases totally unexpected. Like that is relevant... And the children are so beautiful. The idea that someone could think they are somehow less worthy of a life makes me livid. Life is tough at the moment, but you know what I have become a much nicer person because I have my gorgeous gorgeous DD2.
