I think your original framing was pretty insightful. There are unpleasant parts about having kids. That could be banal stuff, like a baby crying when you're tired or getting annoyed by kids movies or songs. It could be more significant stuff. There's a vulnerability that comes from having something so precious exposed to the world. Imagine laying in bed at 3 am contemplating the unsettlingly non-zero chance your baby could just die for no reason. Unpleasant is underselling it. It's a sign of immaturity to avoid unpleasant but worthwhile things. Like a child who doesn't want to brush his teeth or eat vegetables. Conversely, it's a sign of maturity to be willing to be willing to overcome obstacles, even unpleasant ones, and make sacrifices, to do things that are worthwhile.
