I was told by the midwives last time it was a shortage of magnesuim I think, or maybe potassium.... but anyway they said pregnancy multivitamens would help.

I also added spinach, and more greens to my diets and they seem to have helped. Bananas are high in potassium as are avocados which are in season so maybe adding those too? All the leafy greens have both potassium & magnesium in great amounts so maybe just adding them to cover both sides LOL... (I'm sitting here looking at my natropath's guide to vitamens & minerals found in particular foods LOL)
