Update 12/20/21
Leo had a good weekend. He didn't have any events, and the ibuprofen seems to be working to shrink his PDA. He had an echo this morning that confirmed the PDA was a little bit smaller. He has been getting a little less fluid in order to keep less volume flowing across the PDA. I was a little worried about that at first, but he continues to gain weight. The doctors also checked his hematocrit levels, and they were a little low. That means he's going to get a blood transfusion later on this afternoon. It'll be his second one.
