The baby has been running around all night for three nights like a wild thing. I think that the mucus is really disturbing our sleep. But even in the middle of the night, I start to remove it and he wakes up, and then I barely manage to put him back to sleep. I can't even imagine what to do. And I rinse, suck out, and inject drops.
