Ds 8 months is at the tail end of an illness that he had antibiotics for. He's alot perkier and no temperature but he randomly gets bouts of the runniest nose. He can't breathe through his nose or feed when it happens, naps and night sleep are to pot too. But then it will just dry up for a couple of hours? It's not like it when he first wakes up either. I'm so confused... Any ideas? Or how to help him. When it happens he's so miserable understandably.
