Butttoucher is full of bullshit (see below) folks. Don't get your medical advice from anonymous people on social media folks.

SIDS didn't exist before childhood vaccinations.

Bullshit.

"when the use of cribs became common in the early 20th century and the magnitude of the problem [SIDS] did not substantially decrease. In fact, the response in England was simply a new name, “crib death,”" James R. Wright, Jr., MD PhD https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6474527/

"Sudden death in a seemingly healthy infant during sleep is not a phenomenon of modern times, with cases being recorded throughout history for thousands of years." Jhodie R Duncan, PhD and Roger W Byard, MBBS, MD. https://www.ncbi.nlm.nih.gov/books/NBK513399/

Japan stopped vaccinating before 2

Bullshit.

Here's the Vaccination Schedule Recommended by the Japan Pediatric Society: https://www.jpeds.or.jp/uploads/files/2020%20English%20JPS%20Immunization%20Schedule.pdf

Japan has no autism

Bullshit.

"The rate of autism in Japan—about one in 55 children—is nearly twice as high as the rate in many other countries including China and the United Kingdom. (The prevalence of autism in the U.S. is said to be one in 44 children, one of the highest rates in the world.)" Lawrence T. White Ph.D. https://www.psychologytoday.com/ca/blog/culture-conscious/202307/is-life-easier-for-autistic-people-in-japan

Japan has no SIDS

Bullshit.

"SIDS ... emerged to be number 3 and 2 cause of infant and postneonatal death in Japan respectively." Hiroshi Nishida, Toshiko Sawaguchi & Stephanie Fukui https://www.nature.com/articles/pr1999959z

Japan has no chronic allergy issues

Bullshit.

From 'Allergic Disorders and Risk of Anemia in Japanese Children'...
"The prevalence rates of asthma, AD, allergic rhinitis, allergic rhinoconjunctivitis, and food allergy were 7.5, 13.0, 28.2, 2.9, and 11.1%, respectively. Overall, 34,967 (43.7%) children suffered from an allergy in the study cohort." Multiple authors - see link: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9607270/

if Butttoucher wants to maintain her claims about the Amish she better provide some proof.
