Hi Daisy.
Welcome
I have a 5 yo son so I have done the maternal diet.
Before him I actually practiced the preconception diet for a few years!
It can be scary and I could not imagine I could be so consistant but you can do it.
And once you are pregnant the motivation is enough to become an instant expert! I found when I was actually pregnant it was much easier because I enjoyed the fresh food even more.
Good luck
