Pocket fitteds are our nighttime dipes. We use Harleyz hemp, FCB envelopes (well, envelope b/c we have only 1), Schnoogly UNDers and a HUGE Litte Rain Dancers fleece pocket. And we cover the dipe with whatever wool will fit! It works great as a nighttime system. Ian nurses all night, so we're in basically the same situation that you are. I've never used Happy Hempys, sorry.
