Can you tell us what’s in store for the Yates family in There She Goes?

Big changes for everyone as Ben and Rosie are growing up and Simon and Emily are coming to terms with what that might mean for them all. Dealing in real time with finally getting a definitive diagnosis of Rosie’s condition and the rollercoaster of emotions it brings.

Flash backs to the moment Emily and Simon considered having a third - how the pros and cons were not what they expected and how ultimately making that decision together brought them closer.

What was it like working with the cast again?

Miley and Edan are still a complete delight - growing into fine accomplished young actors, it was wonderful to see them again. David Tennant was as always brilliant, effortless and joyful to work with.

Simon and Emily make a number of cult references throughout the two series and the special, are there any that are particularly memorable?

I can't remember any which proves I am a fraudulent nerd.

Have you received messages from parents in similar situations to Simon and Emily?

I’m not on any social media, so no, but I have had letters of congratulations and requests to be part of Learning-Disabled charities which is a great honour.

Did you bring any of your own parenting experiences to the role?

Instinctively yes, I think so. Rosie bashes a soup spoon out of my hand in the scene and I picked it up, put it in my mouth to clean it quickly and then offered her the soup again (which she doesn't take) - that is a reflex from being a mum and spoon feeding toddlers.

What is it about Shaun and Sarah’s writing that makes this show appeal to you?

To work with artists like Shaun and Sarah has been one of the privileges of my career. I am in in awe of their bravery, honesty, humour and skill in creating this important family story with flawed, funny, truthful characters. Also, they give me lots of lines, which I like.

What do you think viewers will take away from the special?

That life is a crazy, amazing, random gift that will only ever make sense if you always lead with love.
