The programme examines the issues around Down’s Syndrome with intellectual rigour but is also extremely moving, largely because of Phillips herself who made the decision to include Olly in the film. He emerges as a chatty, engaging and kind little boy who often has his younger siblings, Luke, nine, and Tom, four, in hysterics.

People aren’t fascinated by the things people with Down’s Syndrome can do better, which are: relate to people, be funny, be comfortable in their own bodies

When she told her younger children their older brother had Down’s Syndrome, Luke responded, ‘and have I got Up Syndrome?’, says Phillips. 

‘And then to Tom, I said, “You have to understand, sometimes Olly doesn’t understand and he gets angry.” And Tom said, “What, like Dad?”’

After the initial teary conversation in the hospital, she was expecting tragedy. Instead, she got comedy.

‘I suppose I always like absurd scenarios,’ she acknowledges. ‘I just started noticing that it was funny… So, for example, when Olly ran away wearing a Leo Sayer wigand outsized sunglasses in the shape of stars and you’re chasing him down the road barefoot, it’s: “Ok, this isn’t that different from work.”…I mean, he’s got great comic timing. He’s naturally incredibly funny. Always has been.’

Of course, Phillips and her husband were often intenselystressed or in denial during those first five years. Of course, it took a period of adjustment.

Naturally, it wasn’texactly what they had expected parenthood to be, and sometimes it required help from live-in nannies and grandparents (something which Phillips admits she is lucky to be able to afford). But, in other ways, it was better.
