Telling his kids apart is easy in the present day, but the past is another story for father of fiveJames Van Der Beek.

The only problem? Van Der Beek, 42, had no idea which of his children — sonJoshua, 7, plus daughtersGwendolyn, 9 months,Emilia, 3, Annabel Leah, 5, andOlivia, 8½ — was in the snap with him.

“I’m guessing Olivia … but could be Joshua,” theDawson’s Creekalum replied.

Kimberly quipped in a confident follow-up comment, “Actually … I think Olivia.”

The date stamp may have given the parents a clue, though. As Van Der Beek explained in a reply to his wife’s latter remark, “Just checked the date on the photo. If it’s correct (and not the date it was imported or screen-grabbed) … this is Annabel,” adding wide-eyed, red heart and crying-laughing emojis.
