Q. My 15-year-old son goes back and forth between his father’s home and mine. Yesterday I was talking to his bonus mom (my co-parent’s wife) and she mentioned his favorite food at their house. I was shocked. He never eats burritos at our house, and I told her so. I told her about his favorite food at my house — french fries from the air fryer— and she laughed. They don’t have an air fryer and he never eats french fries there. I’m so afraid there is something psychologically wrong here and we have tried so hard to make it easy on him. What’s good ex-etiquette?

A. There may be some psychological issue, but I can’t say that based on what you describe. It’s more that he has compartmentalized his eating habits. Burritos at dads, french fries at mom’s. Dad doesn’t have an air fryer, so he found something he liked that didn’t require one. You could look at the deep psychological reasons behind it, but short of getting him into counseling, it sounds like he’s just learning to cope with what is before him.

Living in two homes is not easy — I think we will all agree — and humans find different ways to cope with difficult situations. Since you were just chatting with his bonus mom, that tells me, as you say, that you have worked hard to rise above any possible animosity between homes. But he still may need some soothing, and eating one’s favorite foods is often the way we do that. Although looking to food to sooth our emotions is not recommended, he’s still 15, and 15-year-old boys fill their bodies with just about anything they can get their hands on when they are hungry.

The thing that is important about this situation is that you have created an environment where you can talk about it. Your son can weigh in, you have discussed it with the other home, and if there was a problem, you have a way to solve it together. You can’t get any better ex-etiquette than that. Keep up the good work.
