Fertile soil
We are both firm beleivers that the healthier you are, and the healthier you live pre-conception, the easier it will be (and hopefully, the better the outcome).
Naomi has been lacto-ovo-vegetarian for 13 years. Cory eats predominantly vego (hey... it's easier). Both of us also exercise regularly and over Summer even competed in a 'Fun'-TriAthlon series (still not too sure where the fun bit is - apart from the finish line).
We also indulge in the odd beverage occasionally - probably a little too much if we were serious about having a kid. But then... we weren't really planning on it working too well straight away - even with all the practice!
We've had quite a few friends who have struggled to get pregnant, and then started living healthier, less stressful lives and have fallen in straight away. That - and a little google-research proved to us that living healthy was the way to go.
