Pregnancy and birth ($3k to $10k) + daycare ($18k to $30k per year) + sickness needing doctor ($300 per visit). I probably got to $130k+ per kid before hitting kindergarten, for 2 kids with no chronic healthcare needs.

And I needed a flexible job that allows you to work from home or be off as necessary to take care of sick kids.

This looks right for what it lists but it misses many costs. You also need a bigger house to support the kids, and a bigger car to carry them around, plus car seats, food, clothes, toys, and furniture. They will destroy parts of your house and some of your stuff and you'll need replacements. You'll be spending much more time and money cleaning.

They will make every vacation more expensive in terms of lodging, travel, food, and activities.

You'll be paying not just for gifts for them, but for their friends' birthdays, and holiday gifts for their teachers. You'll pay for admission to parks, memberships, and other activities you take them to to keep them busy and help them develop.

Even if they go to public school, you'll be paying for before and after care, extra classes, activities, equipment, lessons, tutoring, and so on. Their various support systems will ask for donations. You'll have to pay for babysitters until they reach the age where they can be unattended.

The total cost is tremendous and hard to estimate.

(I say this all as someone who thinks it is worth it and who 100% supports having children for people who are in stable relationships and who can afford it!)
