Be careful of the Gender Dreaming website. She has her own agenda - selling her "personalised sway plans". I was doing a lot of sway research and bought a "girl/low everything" plan. Complete rubbish, lots of contradictions, nothing personalised and quite frankly dangerous nutritionally. No actual studies, just her "interpretation" of other studies iykwim. She also gets really narky if you ask any challenging questions.

I used the Shettle's Method after much reading and research. It's been around a long time It worked for us!
