G.S.
I agree with the other moms here, CIO is definitely not for children who are sick or in pain. I personally don't think it's a good method at all and it upsets me that people use it with their children. My daughter is 9 months old and whenever she is sick or in pain I let her sleep with me. I usually just hold her on my chest. It works for both of us, we both sleep better and I enjoy the closeness.
