So basically it seems like CIO isn't so bad so long as its not for an extended period of time. In my case my LO (and myself) are just not made for CIO. He will scream relentlessly. But it seems for some it can work and its just fine if it only takes a few days. Not for me personally at this point but I feel like this is nice to know for moms who have to CIO a bit to get any sleep.
