Granted, teddy bears are one of the trademark easter eggs of CoD all around, but considering how strongly they're tied with Samantha when applicable and there's no other little girls in the series (other than young miss Davis), as well as there reading "Sam" or "Sami" on the adjacent wall it's more likely than not.
