I have accidentally found myself in the co-sleeping camp, and I'm sure you've all seen my previous posts on dd's sleep, or lack of it.
She is very unsettled in the evening, as if she is waiting for the time when I will put her in with us. I feel the co-sleeping is encouraging her evening wakings.
Have any co-sleepers had this problem? Or have your dc's gone to bed at the same time as you? Not an option for me.
