Third time lucky?

I have two kids- one three and a bit the other 20 months old. Everything was fine with my first. Good experience all around. However, with my second I suffered and so did my baby! I had severe anemia both during pregnancy and after. I also suffered with post natal depression. My daughter had quite severe eczema for the first year of her life and still flares up occassionally. After months and months of research I am convinced that her eczema problem was directly linked to a Candida problem I have suffered with for years. I have also struggled with metal toxicity and other related colon problems. I recently put myself through a 30 day juice fast with amazing results! I feel better than I have in years and would like to continue to detox and heal. The reason I am writing this is my husband and I have decided to have one more baby and to begin to try at the end of the year. I have been reading a lot about parasite and Liver Cleansing and wondered if this was the best way to go to prepare my body. I was also wondering if anyone has experienced help with morning sickness. I was horribly sick with my first two pregnancies but I was wondering/hoping that if I am in better health I may not be so ill!
