Well, it finally happened. Adam's outie deflated. He had quite the belly button protrusion, we thought mostly from having more tummy issues in the NICU. It was really weird - you would push on it and could hear fluid and air gurgling inside. Kind of creepy, actually. The doctor said it was part of his intestine wall and would go away probably in the next year. But low and behold, Saturday evening we changed his diaper and it wasn't sticking out any more. And it seems to be staying flat.
