Monaco’s Prince Jacques and Princess Gabriella will turn 1 on December 10 – and their father admits he’s not sure what to give them.

“I’ve a few things in mind,” Prince Albert confides to PEOPLE, “but I really haven’t decided yet whether to give them something significant, which they’ll keep for years to come, or just give them better toys than they already have in the nursery.

“I suppose I could do both,” he suggests, adding, “probably should.”

The arrival last year of twins Crown Prince Jacques Honoré Rainier, the Marquis of Baux, and Gabriella, Thérèse Marie, Countess of Carladès was heralded by proclamation and celebrated with a national holiday.

When the babies – or bah-bahs as Albert and his wife Princess Charlene call them in private – turn 1 next week, there’ll be considerably less fanfare.

“I think from now on and in the immediate coming years, their birthdays ought to be more private events,” says Albert.

Despite commitments to be in Paris for COP 21 until it ends on December 11, Albert will return to Monaco on December 10 for the twins’ special day.

“We may be visiting a school with the children,” he tells PEOPLE of their plans, “but that will be in the morning. The rest of the day will be for family only. I’ve set the day aside, I’ve no other appointments, we just want the family time.”

Like any proud parent, he admits, “I want to take some pictures, some movies of them, so it’s just going to be a family day.”

“I’ve had a great many events, trips and functions lately. Today, for example, I’d few events I had to attend but I was able to be with them earlier this afternoon.

“We had some beautiful sunshine and they’re beginning to experience some of the swings we still have from the old days in the garden.

“It was great,” he reflects. “Just a beautiful day.”
