Why do several of the men call their wives “baby” after like 3-4 days?

Just so icky. None of the women seem bothered by it, & they’ve known the guys like less than a week? It feels like very forced and every time I hear it, I want to cringe. The men who do it (Adam & Felipe) are especially icky, and the women (Tori & Marissa) have vocal fry and think it’s so endearing when the guys call them baby after only a few days. Is it just me, or is this just ick? I don’t want someone calling me that when they barely know me. What is with this cast?!?
