I lost all my bookmarked links, so I need some help. A friend is considering letting her 8 week old CIO for naps and overnight sleeping...can someone please point me to some sources that explain why this is a bad idea? I'm going to recommend she look at Happiest Baby On the BLOCK, Baby Whisperer, and/or NCSS. Any other alternatives to cio that you'd recommend?

Re: Help! Why shouldn't an 8 week old cio?
I'd also rec. Ferber- it'd probably be easier for her to believe coming from someone who doesn't see all CIO as bad.

or even the wikipedia page talks about his rec. age range.
ETA: this on may be good too: https://www.parentingscience.com/Ferber-method.html
