There's no simple way out of this, but a lot of alignment and discussion is certainly needed between husband and wife. No right or wrong in this case, whether no kids, one, two, three or even more. Most importantly, must agree as one (husband and wife) and move forward together.
I myself have 3 kids, started with 2 boys and accident a third (girl....luckily). Me and my wife are both working, we can afford to bring them up in a comfortable manner, but it does take a toll on our physical and mental health at times. Time is never enough for us, but that's where we have to align, discuss, split task and conquer accordingly. There's a lof of joy in having kids, without a doubt.

Me and my wife don't expect our kids to take care of us when we grow old, or to support us and accompany us through our golden years. They owe us nothing. It is our conscious choice to have them and raise them unconditionally.

All the best in going through this!
