Actor and writer Rob Delaney has said that were it not for his wife, he could not have got through his grief, after his two-year-old son died from cancer in January 2018.

The Catastrophe star said of his wife, whom he fell in love with at first sight when volunteering at a camp for people with disabilities, that: ''Part of our love is navigating grief together and I couldn't do it without her.''

The pair have three other sons ranging from six months to six years of age.

He said that the baby was of no consolation after the death of Henry: ''It's sort of like they touch each other a little bit, but they almost exist in separate lanes. Having another child in no way, shape or form eases the grief of Henry dying.

[But it also] doesn't make our new son any less magical. I want to gobble him up and he deserves our full attention and love, and he grew in the same womb as Henry.'' He said.

Speaking to Marie Claire magazine he said: ''We likely would've had a fourth anyway. But I mean, there's mixed feelings."
