When you think 'I can tell my babies from others' and then you realize that no... you can't! 0.o
And yes, since they are harbor seals the babies aren't white.
More funny Parenthood material, this time featuring an alternative universe, where Julie is a selkie who fell in love with a human named Darrick Hunter... and he found it out when she gave birth to two little seals. Yeah, pretty shocking. XD

Inspired by this story (warning for hetero sex)

For more about alternative universes with these and other characters look in my AvP folder

I own humanized Karnak (Darrick Hunter), and partially Julie, while  theoracledragon owns partially Julie. We don't own selkie.
