How far?

My dh & I were talking about how far we would go in our journey of having a child. I think we decided that it all depends on the cost. If IUI's & IVF's are too much we won't do it. As badly as we want a child together we still have the twins to consider. We don't want to go broke having a kid & then struggle to make ends meet when s/he is here (I've been down that road & not willing to do that to our kids). Who knows we may change our minds but that's what we are saying now. I'm not sure if the cost where everyone is but I'm told for those treatments  start at around $5000. That's the cost on 1 years summer camp by me. Although I have to admit that it we couldn't have a child together a large part of me would be devestated. I want nothing more than this.
