"Oh, you think your Ma is better than me, huh?" Alistair chuckles, holding your four-year-old up in the air and pressing the tip of his nose to theirs, causing them to giggle. He gives you a scrunched-up look of amusement as he does this, almost like he can't believe the words coming out of his own kid's mouth. This is all playful banter, and Alistair knows not to take such words to heart, but it's fun to mess around once in a while.
It's not that your kid really means their words, either. They're just behaving that way because they can, because Alistair lets them act like a brat sometimes. He puts on a feigned look of hurt as he turns back to your kid, pouting playfully. "After all that I've done for you, hon. All of that spoiling and affection. This is what I get? What am I going to do now that I know I'm not your favorite?"
