so we are attempting the CIO method on our son and I would say it's a fail! It's been an hour and a half and I feel like he is still just as awake as he was initially. We stopped going in there to reassure at this point because it just makes him scream more. I guarantee if we went in their he would fall asleep in our arms within 2 minutes but I feel like if we do at this point all our effort is wasted. Is this lasting too long or should I sit and bear it (all while my husband is snoring and believes "support" means one sleeps while the other, meaning me, sits and listens to the crying).
Re: Cry it out
There's a section after Ferber introduces the "progressive waiting" approach where he talks about if it's not working and offers some trouble shooting advice...I would go look at those.
Remember, the point is to change baby's sleep associations and get baby to fall asleep on their own, not cry themselves to sleep. I would set a number of days that you can stand it (I decided I could do 3 days) and reevaluate if everyone is ready for this and if not, back up, think about it, and try again in a few weeks.
You are not an awful parent, your child will still be attached to you and love you, and you can still meet your child's needs. You are just being practical. There will be tears whenever you stop holding them to sleep, be it now, in 3 months, after a year, or even 2-3 years.
