We had his first appointment today, at about 4.5 days old. He was already back up to his birth weight, yay! He didn't lose that much weight in the hospital, only 4oz, so we had a good starting point. He's a little yellow, so the doc wants us to watch for signs of worsening jaundice, but to be honest, he's nowhere NEAR as yellow as my DS2 was, and she wasn't concerned about him. He's eating well and pooping a TON, so I'm sure it will resolve itself. Otherwise, everything looked good.
