Start living on one income now. We started 6 months before we started TTC. It means that we are now completely used to one income, and also have a good amount of savings behind us should we need it (we haven't touched it yet) I am staying at home comfortably, and have no plans to go back to work unless I decide I want to.

Get fit - I know you've got healthy eating in there, but physical exercise is great too. I was pretty fit before pregnancy, and very active during, and I think it helped me all the way through, incuding labour, birth and recovery.

I can't think of anything else that you haven't covered. So exciting!
