For the most part, nursing is still going OK for us, though last night she decided to bite - hard! - when I was nursing her in the middle of the night, which she's only done a handful of times in her life. It would hurt in any case, but *really* hurts now with my already-sore boobs.
We're also down to nursing generally 2-3 times a day (before bed, when she gets up in the morning, and usually once during the night) which is very manageable. However, I think I may be one of the only people on this thread who does hope that DD weans during this pregnancy. I love the idea of tandem nursing in theory, but it also just sounds a little overwhelming to me, especially with FT work and pumping. I'm not really sure the best way to encourage it, since I don't want it to be too close to the new baby's arrival (which might exacerbate feelings of jealousy), but also want to let her nurse for a while longer.
This was also a surprise pregnancy for us - I didn't expect to be dealing with these nursing/pregnancy issues quite so soon...
