Prince Harry looked a picture of happiness as he was welcomed with cheers in Oxford this morning for his second royal engagement since becoming a father.
The Duke is spending the day visiting organisations supporting sick children, disabled adults and young people from disadvantaged backgrounds.
His first stop is a children's hospital where crowds lined up outside keen to catch a glimpse of him.
The Duke beamed as 13-year-old former patient Daisy Wingrove gave him a locally made 'Witney' teddy bear wearing a special t-shirt for his newborn son, Archie.
Harry also joined in with the chorus of 'awwws' coming from the crowds and couldn't stop giggling before taking the time to kneel down and speak to some children.

Just last Monday the 34-year-old welcomed son Archie into the world and has left him in the care of wife Meghan Markle and mother-in-law Doria Ragland at Frogmore Cottage in Windsor.
And he told one mum this morning he’s ‘still getting used to the idea that he’s a parent himself’.
Last week he also jetted to Holland to launch the one-year countdown to the Invictus Games 2020 at The Hague.
It had previously been reported Harry would take two weeks paternity leave on the birth of his baby to show he was a "modern dad".
However a friend of the prince is also reported to have said: "He doesn't need to take paternity leave because he doesn't work in the way most people do but he thinks it's a very modern dad thing to do."

During his first visit today - at Oxford Children's Hospital, a purpose-built centre for the treatment of children and young adults, based at the John Radcliffe hospital site - Harry met mum Amy, son Emmett and her four-week-old daughter Ida.
The pair swapped parenting tips, with Harry admitting he was still getting used to becoming a dad.
He also stopped and played with dinosaurs with some other youngsters in one of the playrooms.
He will later meet teenagers on a ward specifically tailored to the needs of young adults and catch up with 13-year-old Mikayla Beames, a WellChild award winner, who previously met the duke at the charity's awards in 2016.
The teen, who has been fighting brain cancer since she was four and is registered blind, is expected to give a special gift to Harry that she has had made for baby Archie.
