Weird Message framing from another Luvs Commercial

First, we've got a woman interviewing a potential babysitter who has a degree in Early Childhood Education but doesn't have a PhD and that's a problem, because to earn the right to be paid $6 an hour to watch a kid suck on fake car keys for a few hours you kind of need a PhD. 

But by the time this woman has her second kid she has no more f--ks to give and is perfeclty willing to hand that second kid off to whichever teen girl is willing to sit in her house texting her friends in the near-vicinity of that baby, or both kids, or whatever.

The unintentionally hilarious tagline is that "more mothers of second children prefer Luvs."  The strong implication is that FIRST moms are really, really concerned about their kids' safety and comfort, but women who are moms for the SECOND time are willing to settle for much, much less.  Luvs is the annomymous teen babysitter to the Other Brand's Early Childhood Education Degree. 

I wonder why they don't just put this message in the tagline- "Luvs Diapers:  When you realize that there's nothing special about kids and diapers are just diapers."
