Unlike some others, when I read through the OP's post, I get the sense that she and her partner do want a kid. She says DH is getting "the fever;" he can talk about wanting to give a child the opportunities he never had etc etc, but there's really no other way to describe it other than a "fever" when someone truly wants to have a kid. Also, I don't read the OP's desire to "outsource motherhood" as a signal that she doesn't want a kid. Motherhood in our day and age seems to be this impossible ideal; I am a mother, and when I read about it in books / magazines / blogs, I want to have nothing to do with it, either. Fatherhood seems a much more reasonable alternative. Except maybe for 2 people who are already FI, caretaking is such a huge job that some of it has to be out-sourced. If not to friends / family, then nanny / sitters / daycare.
OP: If you are closer to 33 than 34, I think you can consider waiting 1 more year to get your health / finances / other stuff in order before trying. Your OB is looking at things from a medical / biological point of view exclusively. But in 1 year, you will have at least 400k in savings and be 2/3 through the contract that, while giving you the high income, is making both of you unhappy in other ways. If neither of you has any fertility issues, you have an 80% chance of getting pregnant within 3 months. So chances are you would still have your child at <35yo even if you wait a year.
70k spend is high for two people with no kids who want to reach FI ASAP, unless you are in an extremely HCOL area and spend 50k or something for housing and health care. We live in a HCOL area (NYC), and excluding daycare, we spend less than than 70k for the three of us, including ~5 plane trips and ~35k each year for housing. Of course, the cost of daycare here blows almost everything else out of the water. For two people, it would be pretty easy to spend no more than $20-25k in addition to housing costs. Any reduction in spending right now might seem trivial with your current huge salaries, but if you're able to live on a lower budget now, you'd have more options when you have a kid, including: 1) one or both of you going part-time, and 2) quitting the high-paying contract jobs and moving somewhere with friends and family.
My husband and I were truly on the fence. We were together for 10 years and waited until I was 38 before having our kid. We made this decision with the full knowledge that fertility for women starts going down significantly at 35, and the risk of genetic problems such as Down syndrome starts going up significantly. We took that gamble because our lives were also pretty great before we had our kid, and we would truly have been OK if pregnancy didn't work out for us. We would have maybe adopted a 4-5yo kid. I consider 38 to be the outside limit for women if they are serious about having biological kids. I know people who waited until their later 30s and were not able to have biological kids, so I would not recommend this path to you unless you truly, truly are on the fence.
