My best advice on the swelling is also to drink lots of water I drink at least a gallon a day if not more.. no good for the peeing situation but very good for swelling. I had some problems with swelling with my first two and the only differnce realyl this time is i drink as much water as i can get into me. Hope all goes well.. I know the nicu is a scarey prospect. my second had to go not because of being a preemie but b/c he had severe jaundice.best wishes. hope all goes well.
