Really hard to approach what is clearly an emotional desire with a logical solution. Anyone married will tell you how that will go...

I have a couple friends who have been in this very situation, all of them ended up with the extra kid except for one who actually ended up divorced (great pep talk hey!). It is a challenging topic because for most women (that I know anyway) kids are the ultimate. That isn't meant to be demeaning to the role of women or to suggest that men don't care about kids...its just different. We are wired different. If the desire/need is strong enough for a women then it will happen. Men are more likely to concede, eventually, to something they are not 100% into, sadly.

As mentioned by many it's an incredibly tricky topic and for the sake of your relationship it should be broached with a 3rd party (counselor etc). Otherwise it is a big enough topic that it could spiral into something that you wont be able to come back from. Either by having a kid that you didn't really want and the long-term resentment that might build with that, or by not providing the kid that your wife so deeply wanted; either way, not good.

Best of luck man...that's a tricky one.
