Ben - I think the secret here for yours and Meg's sanity is accepting as well as you can that babies do exactly what Isabell is doing. Whether you advocate CC or would fight against it with all you have, babies cry! It is exhausting. It can be demoralising, depressing and frustrating but that's the package deal. My DD#1 had all her day sleeps on me for the first 5 months and then we graduated to her going to sleep on me so I could then put her down. It took until 10 months of age for us to be able to put her down for the night at 7.30 pm. Until then it was anything up until 11pm. I found I went pretty nutty fighting her to get it any other way and as soon as I accepted it, the better it was for all of us. You definitely need to still keep trying to get her to settle on her own, but your little girl is so tiny. If she goes to sleep better while you're holding her, look at it as the blessing it is that you are cradling your daughter in your arms.

And like someone said previously (sorry - forgot who), you will think you've got it going perfectly and something else will happen - a growth spurt, a tooth, a cold etc and it will all go out the window again for a while.

Hang in there, take deep breaths and try to see beyond the screaming so you can enjoy this very precious time with your daughter because they grow way too damn fast.
