He's been in the NICU shortly after birth from breathing problems, just found out he has PDA (Patent Ductus Arteriosus) The doctors say it's uncommon for a baby his size to have this, they are letting him have some time to see if it will close on it's own. They plan to do another heart echo on him Monday morning to see if there is any improvement. If not, they will start to give him medicine to try to help close it. Just wondering if anyone else has had any experience with this?
