You were just thinking about it. Yet, that doesn't mean you are ready for such an enormous committment. Children are extremely expensive and you can't just suddenly decide you don't want a child once you have one either. If your wife is not working, is not able to be independent she should not be thinking about having a child. And the two of you DEFINITELY need your relationship to be rock solid too. You have challenges you have shared here with your wife, the two of you have to sort that out first. You actually should give your marriage time before even thinking about having a child. Children put a lot of strain on a relationship too so if the relationship is weak then what? And if you broke up you are not working and can barely support yourself and your wife, she won't be able to get child support.

My suggestion? Get her a puppy and see how she does with that first. Puppies are a lot of work, but not as much as a human baby would be. Also, you always have to be prepared for a child that may have special needs too. There is no certainty when having a child that it will be perfect like some fairytale.

Also, being that she is all about a baby now, if she has one she will be all about the baby and will have even less time for you and your relationship.
