Honestly I think if you both desire a child than the rest is just details. My DH and I waited 8 years before having our first. And then we just had our second who was born the day after her sister's 7th birthday. Although we had some fertility issues that played into our timing it is working. DD1 is jealous of the baby, but she is also her biggest fan. As far as finances....we waited until we felt "secure" only for DH to lose his job while I was pregnant with DD1. Then I was let go from my job of 11 years about 3 weeks after returning from maternity leave. However we are just fine and I wouldn't change a thing.
