There's a difference between using kid-talk as a way to find common ground and bond with other people, and being literally unable to talk about anything but your kids. That latter bit actually does happen with a disturbingly-significant number of my friends who are parents.
The main commonality among parents I know who are afflicted with this problem is that they have no or few relatives living nearby. Those who have relatives (especially their own parents) nearby seem to be more well adjusted. While they still talk about their kids a lot, they can at least speak about other interests and events unrelated to the kids.
One of my friends who also is able to talk about other things is a freelancer and is not a workaholic. I suspect number of hours worked to be correlated here too.
Don’t people do this regardless though? Most people mainly talk about themselves and their interests. Kids are just a very common interest.
There are also a lot of people out there who only talk about work, or tech, or sports, or who hooked up with who, and anyone else who doesn’t share that interest will be bored to tears hearing them go on and on and about it.
