Because I can't cope with the lack of sleep? My DD is 10 months and just will not sleep through at the moment. I assume it's her teeth. Or it's too hot. Or she just doesn't want to. But I'm 37, and feel I'm too old for this! All I want is a full nights sleep! Does this melt into the back of your memory like childbirth where you forget how bad it was eventually so then you don't mind doing it again??
