Rob Delaney is opening up about a joyous new arrival, revealing that he and wife Leah welcomed their fourth son in August, just seven months after the tragic death of their two-year-old son Henry.

Speaking with the Sunday Times, the “Catastrophe” star spoke about the couple’s “mixed feelings” about having another child under such terrible circumstances.

“It’s sort of like they touch each other a little bit, but they almost exist in separate lanes,” he says of welcoming a new son after saying goodbye to Henry. “Having another child in no way, shape or form eases the grief of Henry dying. But also having Henry dying 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.”

As Delaney, 41, tells the Sunday Times, emotions are still raw for he and his wife after Henry’s death due to a malignant brain tumour, yet that doesn’t necessarily mean they’re engulfed in grief every waking moment.

“Here’s the thing. I had a big cry earlier today about Henry. My wife and I also had a big laugh earlier today. It might surprise somebody to find the parents of a child who died 11 months ago really laughing, but grief for me has not made other emotions impossible,” he says. “It has introduced a new mood or feeling I never knew before, and is profound. But jokes are still funny, things that piss me off can still make me angry, sad can be sad, exciting can be exciting.”

Delaney also discusses why he and his wife decided to keep Henry’s illness a secret, but why they had no choice but to go public when he died. “It would have been impossible for me to hide it away, because the pressure within myself, if I had to stuff that down, would make people go, like, what happened? What went wrong?” he says.

Whenever Delaney is asked how he is, whoever asks the question has a tendency to add, “Oh my God, that’s a stupid question,” he says, but says he’s quick to tell them it isn’t a stupid question at all — “If you’re ready to hear the answer,” he adds.

“The answer is my heart hurts, OK? I had trouble getting out of bed today, and I cried before I got up,” he continues. “And then I had a cup of coffee, played with my other kids, came and said hello to my wife, and then I started to feel better. Then I got sad again. So I love that question. I tell people, I’m a balloon that is filled almost to the point of bursting, and when you bring up my dead son, it’s like you’ve let a little out. It’s like a gift.”

Earlier, Delaney shared his feelings about Henry’s passing in a series of Twitter posts as he and his family marked their first Christmas without him.
