Crying it out!!! Am I the only one?

Sadie

So a friend of mine posted on Facebook what to do about her son wanting to be held 24/7 and she can't get anything done so she has been letting him do the "cry it out" method. He's only 1 month old. She posted asking what to do to help. I commented saying it's not suggested to let newborns cry it out due to stress and I included an informative article, and some helpful mom tips I used with my son. Well sooooo many people commented saying they let their kids cry for more than 30 MINUTES and talked about how they were fine and I was wrong for including the article that it meant nothing! I didn't mean to offend anyone but to me it's scary and crazy to let that young of a baby cry themselves to sleep! Am I wrong?
