I'm not going into the bad parents aspect but I doubt this is a "generational trend", you are just entering the stage of life where a lot of people want that. I'm guessing you are between early/mid twenties to mid thirties? That's when people mostly have babies. It's not a "generation" it's just where you and who you surround yourself with are in your/their life progress.
You may not want kids, and that's ok. Some people do especially in that age range.
