Lucy Wright from Craigavon was one of 12 babies born on 22 July last year - the same date as Prince George - who were invited to St James's Park beside Buckingham Palace for the big day.
The one-year-olds and their families were treated like royalty as they enjoyed a picnic on the lawn.
Little Lucy was the only baby from Northern Ireland at the special event in London.
"We joked whenever we found out that whenever I was pregnant and due around the same time, wouldn't it be funny if she was born on the same day," Lucy's mum Diane said.
"Then she was and that was very exciting. Then to find out about this royal event as well was just unbelievable. Obviously Lucy doesn't understand at the minute but it'll be lovely when she does to be able to show her."
Proud dad Richard added: "It was an experience that we never thought of having and it's something that well look back at Lucy will see the photographs when she's older and it'll be a story to tell."
Richard and Diane believe the Duke and Duchess of Cambridge, William and Catherine, seem like "great" parents and have taken a relatively "down-to-earth" approach, for a Royal couple at least.
"They've been very much letting him grow up not so much in the public eye, which I think is lovely, but then he's been out and about a bit to let people see him," Diane added.
To mark the occasion Lucy and the other babies were also given a commemorative five pound coins from the Royal Mint.
