Prince Harry has admitted he is having sleepless nights since the arrival of baby Archie.
But the Duke of Sussex revealed he cannot imagine life without him.
Harry, chatted about fatherhood during the first of a series of visits in Oxford which began with him celebrating the work of the city’s children’s hospital.
Harry, who became a father for the first time last week, was presented with a tiny teddy bear for Archie when he arrived at the hospital.
Daisy Wingrove, 13, a former patient of the hospital, presented the gift to the duke just before he began his tour of the hospital, and Harry let out a big sigh and said ‘Ahhh’ as a nearby crowd of well-wishers made the same sound in sympathy.
Later the duke met parents whose children have been battling cancer on the hospital’s Kamran Jabble ward, named after a former patient.
He spoke to mother-of-two Amy Scullard whose three-year-old son has been diagnosed with testicular cancer.
She said: ‘Harry said he’s getting used to the baby and how Archie has fitted into family life.
‘He said he just feels part of the family and he can’t imagine life without his son.’
Christine George, 52, whose son James, 17, was having chemotherapy, said: ‘He said he had all this organised, but had a sleepless night last night – not the ideal preparation for his first day at work.’
