How old is DD? We have been and are kind of still going through same thing..... We had a reeeeally bad patch when DD was 91/2 - 101/2 months, but although there's not as much sleep fighting and screaming these days, we still have the standing issue.

I don't really have any solutions and just wanted to say hang in there - Like Trish said, I too think it is a developmental thing - but it must be so hard for you going into your 3rd trimester too.....
