Jack cried himself to sleep for a nap today. I dare someone to say something bad about that! Haha. No seriously though, his sleeping has taken a dive the last 2 days. I get him to the whimper/tired cry stage and we do a modified cio at that point. If he is screaming loud though, neither of us can take it and I end up rocking him or something. Luckily, he doesn't sustain that sort of crying for long. I think CIO in some form or another is impossible to avoid unless you co-sleep. If you have ever left your baby's room with them screaming in the background while you tried to prevent yourself from sticking forks in your ears, you have used CIO. Better then the alternative, I say.
