Some of my friends and family who had kids at a young(er) age - and by that, I mean late twenties or early thirties - seemed totally oblivious to the hardships of parenthood.
You’d think by your thirties you’d do some basic research. Most people just have kids because it’s just “what your supposed to do” and don’t give much thought beyond that.
I don’t know what they thought to themselves, but outwardly they projected rainbows and unicorns until reality eventually hit them.
