I have a almost 4 year old and an 18 month old.just found out I'm pregnant again, I'm not sure it's the best thing for us ,husband definitely doesn't want another. It was a mistake. I thought I would like one more,but reality has hit and I'm scared. Financially it would hurt, secondly I would be 42 by the time the baby would be born and lastly I don't want to bring a child into the world that my husband didn't sign up for. Thoughts ? Advice?
