Quoting 1inpink2inblue:" My lo's bilirubin levels went from 12.2 to 17 so we are back in the hospital and he is under lights. ... [snip!] ... (and they should be) then we can leave. I'm so ready for all this worrying to be over with so I can just enjoy my baby. Cry!"
you should check me, but i believe that bilirubin goes in waves
as in, it goes down on days 1 - 4, then up on day 5, then down, then up on day 9, then down again
just be prepared that it *could* spike again, and remember that it will pass!
