Nobody can accuse Daniel Gillies and Rachael Leigh Cook of rushing into a name for their son.
The Originals actor, 39, said it took days after their son was born on April 4 to settle on the perfect name for their progeny: Theodore Vigo Sullivan Gillies.
“We just couldn’t settle on a name because it’s such an important decision,” the actor tells PEOPLE, explaining that he went with nicknames including “sweetheart,” “raisin” and even “calcified alien” in the interim.
The couple had it narrowed down to two names before birth — after compiling individual lists that included upwards of 700 names to start, then creating a sort of “Venn diagram” to see which names overlapped between them, before coming up with their top choices.
