Nick and Judy adopting little newborn bunny kit, and Nick constantly worrying about their growth and development. Like meeting important milestones when they should. But Judy assures him that everything is fine and normal, and tells him to relax.
Then later they adopt a newborn fox kit and Judy is immediately and constantly concerned about their growth and development. So she looks to Nick to support, but he’s just like “I don’t freaking know, why would I freaking know. Crap, our kit’s gonna die, Carrots” and generally freaking out just as much as her. Which of course is no help to the situation. And the two of them are a mess until Mrs. Wilde comes and tells them they’re being ridiculous.
