If you are financially stable that's good but raising a child takes a lot of time, it will eat your youth up. Think twice think thrice. This is the 21st century, if your wife is bored ask her to get a hobby. Kids are no longer a necessity in this modern era.

"I don't wanna say this "but 1 of 10 kids is not normal - use this argument with your wife and tell her you don't wanna take chances.

Emotional blackmail is another thing, you should blackmail her back ask, tell her you will quit your job and get a low pay job and ask her to take responsibility for the finances. (i really hate emotional blackmailing, especially in a 'symbiotic relationship'.
