My baby boy still has a little mucus left in his nose and chest or whatever. The doctor told me it was normal when I left the hospital and that'll he'll be coughing and spitting up every so often until he gets it all out. But my little man only does it when he sleeps. And it scares the living shit out of me!!! 😨 It sounds like he's choking on his own spit and I jump up everytime I hear him to turn him on his side or something to make sure he doesn't choke but he just coughs it up and then acts like nothing happened! Like it didn't even phase him. Y'all my nerves be all messed up when he does that mess. 😖
