It's interesting how Kody claimed that he had to pull away physical affection from Meri during his courtship with Janelle, which also resulted in a lack of public displays of affection with Janelle, too. Based on what was said in the past, the public physical affection with Meri didn't stop and years later he got Janelle to do PDA as well.
On the show, like Christine mentioned in the last episode, Kody would kiss them in front of each other. He kissed all four of them one after the other on one of the Valentine's Days. He also kissed Meri in front of the whole family on her birthday after gifting her a second Mexico trip. A couple of times, he kissed them all goodbye in front of each other. A couple times he kissed Christine in front of Robyn. And on and on.
