I’ll go first: “You have to have children when you’re young,” told to me when I was in my late 20s, with no desire to ever have kids, and no means to support them, by someone divorced multiple times with at least one adult child who does not speak to them.
Also: Responding to “How do I deal with this problem?” questions with “Oh, don’t worry about it, it’s enough that you’re even thinking about it!”
Also, like, adult humans don’t do so good if they only get to sleep for an hour or two at a time. I don’t have kids but I have a puppy and my mental health improved 10x when he stopped waking up every night because he needed to pee. Just going from two 4-hour blocks of sleep to one 8-hour block.
Then he hit puppy adolescence and had a massive sleep regression and I was getting an hour or two of sleep at a time between SCREAMING PUPPY INTERLUDES and promptly lost my fucking mind. I gave up on crating him because I needed the sleep.
