My wife and I really want to have kids of our own.

My name is Belle and my wife is Sunni. We haven't been married for long, but we have been raising her niece since we've been together. We recently took in her nephew as well and that was not in our plans. It is hard to save money at 25 and 27 years old while raising kids half our ages. The only thing that is stopping us from having one of our own is money, unfortunately. My wife wants to have a baby and go through the whole process of being pregnant so bad.
