Jenni - i hope she's ok now. It's hard to cope when you haven't had much sleep. I've been there this week and my little one is 20 months! She has probably only slept through the night 10 times in her life. She has a dummy - so wakes if it's not in her mouth when she stirs. I used to rock her to sleep, but for the past 3 months she's been settling herself to sleep - i think that has helped.
Anyway, I haven't helped at all, but just wanted you to know that you're not alone.
Hope you get some sleep tonight.
