"We had to have some hard conversations about whether to continue with the pregnancy".

Naomi is a midwife and Al is an architect. They are the parents of two boys - Frankie, who is seven and Joe. Joe passed away suddenly just before his second birthday. Only a few months later, Naomi became pregnant. They talk about the decision to terminate the pregnancy when a non-invasive prenatal screening result showed a high chance of a chromosomal deletion. Naomi and Al share what they have learnt about pre-natal screening as they've climbed, in their words, 'the Everest of grief'.
