Tell him he's having 2 birthdays this year.Of course next year you'll have to go one better and give him 3 birthdays. It's better than lying n'est pas.
No, that's not how the progression works. If it's twice as many as the year before it will be 4 next year. In 8 years time he'll be having roughly one and a half birthdays per day.
