But I still feel like pointing something out: Know that phenomenon where users that paid for software are typically more satisfied with it and give better ratings than users who didn't?
Whish I knew what the proper name for it is, but having kids is kind of the ultimate version of that :D
(Update: Thanks so much for helping me figure out what to call it!)

Possibly these:

The more costly it is to make the wrong choice, the more is invested into rationalising the decision, the stronger the bias.
People who think "I think I will likely be happier with children" will be positively correlated with people who have children and are happy about it.
People who think "Having kids will probably make me less happy, so I won't have any." will be negatively correlated with having children, or being happy about them if they do.
This isn't irrational. It's just knowing yourself and choosing wisely.
