worth noting that 2 children is below replacement rate, so someone needs to be having 3 kids too. which is becoming increasingly uncommon especially because of how many things change between 2 and 3 kids. (Notably: 2 carseats fit in ~any vehicle. 3 fit in very few vehicles unless you rush the oldest into a booster seat.)
just want to say that we have had four kids over 6 years in one of the most expensive states in the us, and went from $30k to over $100k in that time frame. It is a huge jump in salary and feel very blessed regardless of the hard work, but just know most of the time was spent below the top end. If you are emotionally stable enough to have a good marriage (and therefore have kids), go for it! You will afford it, and life couldn’t get better!
