Getting your microbiota from your mother is common, even among non-mammals.
Microbes represent essential but non-bodily form of same प्राण that form and sustain body cells. All Mothers (insects, birds, animals) pass on microbes to newborns.
Only humans compromise this microbial-transfer process by several ways. Primarily, way is to neglect breastfeeding. Second – highly sterile home setup. Third – bombardment of antibiotics. Fourth – Mother under constant stress. Fifth – mother engaged in trivial life routine and spending not enough time with kids.
Missing प्राण due to missing simple parenting duties = Entire Generation suffering from Autoimmune diseases.
Think about it. Take care of growing children.
You are absolutely right. When my one year old fell sick with severe diarrhea, an old doctor told me to stop cleaning the floor with dettol. He also told me to breastfeed till she was at least 2 yes which I did.
