My boy is in nicu he was born 2 weeks ago 7 weeks early he was on a breathing tube for a week and a few days he's been on CPAP for a few days and is soon okay. But he has a collapsed right lung and sounds very chesty and has to have suction a few times a day has anyone else's baby had this as I'm worried and if so was wondering how long your baby was in nicu for and how they are doing now
