So we called back the Pediatrician and ended up being seen the day after discharge. This ended up being really important as Milo was a little jaundiced (very common for any newborns, more common in ones born pre-term or right around term), enough that the doctors wanted him to get a jaundice blood test. And the test levels were high enough that he needed to be rechecked the next day.
The most important good news is that his levels were lower the second day, so the docs aren't too worried anymore, and that's great. But once again, it's another example of how you really need to advocate for the care you think is important, which doesn't always match with what your doctor might think.
And while I'm here, why not share another picture of our awesome and definitely not jaundiced little miracle.
