Hagai Tzarfati and his wife Rosie Smallwood have had their lives upended. Since their son Elliot was born a month ago, this Dublin-based couple has been sleep-deprived and are now wondering how they will manage when Hagai goes back to work in a few days.

“I’m dreading it,” he says. “I’ve spent the past month helping Rosie and basically being another pair of hands as we learn how to parent our son. I’ve also had time to bond with him. When I’m back at work, I know I’ll worry about how they’re getting on at home and I’ll be sad to miss out on what Elliot is doing.”
