I don't wish we'd done anything differently, it's all been timed great for us

I wanted to travel (and we did go to Japan in 2006 for 6months) but wanted kids more, but once this next bubba is 1 the plan is to go back to Japan for a couple of years, save more money, then come back in time for DD to start school, and buy a house. We can do Europe etc when we're older
As for things you should do while waiting for IVF - I agree with the others re movies/dinners out, sleep ins (man I miss those lol) and lots of couple time
