Add some sweet potatoes to your diet. They help balance the hormones.
And maybe you need more time to yourself. A difficult thing to do when caring for a little one.
Another thing that helps the hormones a lot is Raw Pumpkin seeds. 2 tablespoons a day. They contain a lot of zinc. You can find them at the health food stores. They are green and have no shells.
A neighbor of mine swears by them. He says they give him a lot of energy and straightened out his hormones. And he is 95!
