On June 20, 2012 I am 26 weeks pregnant and officially in THIRD TRIMESTER.
Our little girl is about 13.6 to 14.8 inches and 1.5 to 2.5 pound range. Her eyes are forming and her eyelashes are now grown. She is getting her immune system ready for
life on the outside by soaking up your antibodies, which is interesting because I’ve been reading a lot lately on "hygiene hypothesis" -- lack of early childhood exposure to infectious agents, symbiotic microorganisms (e.g., gut flora or probiotics), and
parasites increases susceptibility to allergic diseases by suppressing natural development of the immune system. Because of this we fail to induce a Th1 polarized response early in life so as we grow up we are more prone to developing Th2 induced disease. The rise of autoimmune diseases and acute lymphoblastic leukemia in young people in the
developed world has also been linked to the hygiene hypothesis.
In other words a little dirt is actually good for you!
