Baby = Money.

So yay I'm pregnant. My fiancé and I are a fairly young couple. I'm 25 and he is 26. Money is a little tight for us due to some hardship over a job lose for me and a title cut for him.  Will honest and say this baby wasn't planned, but as an adult I am will to accept the consequences to my actions. (Even if I'm more happy than upset) A big argument we have is over money. How does everyone else deal with this. I'm simply looking for tips to reassure my fiancé that it is going to be tight, but we will be ok. I know I can't promise that. No one can. But how would handle my situation.
