Basically, I'm on my knees with lack of sleep. DD is approaching 14 months, is running around, eats well and is still BF but doesn't sleep. She has just cut a rather large back tooth and I suspect there are at least two others just about to pop through. But last night was awful. I just need to know that others have been in this position and got there in the end. It feels like I can't see the light at the end of the tunnel this morning. I was awake with DD from 1.30am until 5am and then had to get up for work an hour later. I drove to work with fat, salty tears of exhaustion rolling down my cheeks. Somebody tell me that it gets better, that she will sleep. I just hope I don't end up in the loony bin before then. . Unless they've got some comfy beds.
