Hi
Firstly I'm a newby too - so welcome to BW. Have you been around the site and/or read any of Tracey's books? We've been following BW since my daughter was 4 months old and I can't recommmend it enough,. She's now 25 months and sleeps through the night, and if she does occasionally wake up , she self soothes herself back to sleep. But, it was only because of BW that we have this. But, I'm no expert - there are some real pros on this site, but as you hadn't had a reply I thought I'd drop a line and say "wow" 5 months of EW and broken nights - you must be so tired - so lots of hugs
.
Just a quick look at your routine would say to me that she is getting overtired by BT which is why she's crying when being put down. To go from 2.30 to 7.30 is 5 hours..may be you could bring BT earlier, or stretch the nap.
We had a problem after a cold with getting back to a full night sleeps. You just have to stick it out, and do WI/WI. It does work, and if she is hysterical, then just don't pick her up, but sooth in the cot, and she will learn that she has to help herself. This is where Traceys books are so good, as she has lots of examples of this. But, warning - it can take a while.
Good luck, I hope others will post and give you more help than this.
