When first researching the subject, I read many accounts of parasites, specifically, helminths, being passed from mother to baby in the womb. Also, it's widely known that they pass from mother to baby in canines, so why would we as mammals be any different?
However, I do not believe everyone has them, and you are not totally sure you do, so don't freak out, yet. I'm sure your baby is fine, but it's good that you are aware and proactive in this situation.
You are cleansing, but not sure you have them though, right? So try to get a positive diagnosis yourself, that way your pediatrican will take you seriously.
When my son was born 26 yrs ago, his original pediatrician was MY pediatrician from birth. He was old school, and probably had seen it all, and knew all about parasites. Today, I would fear dealing with this issue, and having a young child in my care......you have to be careful not to be labeled crazy. Sad but true. Please update what's going on with you.
