The death of a loved one can be a life-changing experience and one that can be difficult to deal with at any age. For children - it is arguably even more harrowing.
He backed up our suggestion that it can be even harder for young people to deal with because many children aren't as emotionally equipped to handle loss as adults.
Young people don't always know about support services and they can often give the impression of having "got over it" when in reality they are simply bottling up their emotions.
Using this guidance as a starting point and after consulting with a number of charities - we ran a short item on our programme asking children who have suffered bereavement and who would be willing to share their stories to get in touch.
We weren't sure if anyone would respond so were somewhat taken aback when lots of children contacted us.
The research stage of the project was tricky - we needed children and their guardians to understand what getting involved in the programme would mean.
We'd be asking about very personal issues and reminding children of difficult times with cameras and lights pointed at them. Not an easy ask.
Some children we spoke to were clearly still traumatised by their experiences so after long discussions with them and their families we ruled them out.
Our overriding objective was always to make a programme that could benefit children - not traumatise them further.
Which is how we ended up focusing on Joe, Bradley, Sarika and Katie. They range in age from eight to 11 and each of them has lost someone close to them.
Putting the programme together has been an intensely moving experience for the team. It's not easy listening to what these children have to say but each of them was adamant that by sharing their experiences - they felt they could help other children facing similar circumstances.
And actually, on balance, it's not at all depressing. There's definite uplift and inspiration in each of their tales and this is what we want our audience to hear.
We have put a considerable amount of work into covering bereavement responsibly with the overall intention of offering guidance and support on a subject that is rarely tackled or discussed in children's programmes.
Watch it if you can and let us know what you think.
UPDATE, 6 April: The programme has now been broadcast and you can watch it below:
