Mel, first of all hugs babe. I know how crappy it feels to have sleepless nights.

A few things occured to me which might be affecting miss m's sleep- have you had her checked out by a doctor? Maybe she has some sort of infection or something. DD has really bad ears for a while before I got them checked out and was sleeping terribly and when she was put on antibiotics and they cleared up, she slept better (not perfect, but better!). Could she be teething? DS is getting his big 2yr molars and we've had several up and down nights. Maybe try the brauers calm/sleep drops (whatever!) several times a night, not just the once. As in giver her some whenever she stirs and is awake enough to take some more. Burn relaxing oils in her room. Have some music/radio/noise in her room. Just quiet, but so it's not totally silent int here all night and it might help prevent her waking when she hears things outside her room? Or when she does wake would she listen to some CD stories or soemthing on headphones (it might help her concerntrate a bit and relax??). Have you thought about an allergy or sensitivity to foods?

That's it for now, lol. I know how desperate you can get. again. It totally sucks. I would take up the offer of some kids free time, even if you're just watching a movie on your own or sitting down to have a cup of tea or something, just relax for a bit without them at you all day. Wish I could help.
