You need to be able to talk to your kids. I have pet names for each one. Like “special one”, “specialty product” etc… I keep coming up with new names. But i ask first. For ibstance I ran loin fruit by its intended target before calling him that and he said no that won’t work. So I respected that. If I had just kept calling him loin fruit or his brother fruit of the loin, that would’ve not been respectful.
