His coughing decreases/stops when he lies down, or is still…and becomes more agitated when hes moving around. He ate a lil food 12 hrs ago. Ive been feeding him water with a plunger because i havent seen him drink anything. But now he just drank a good amount of water on his own. But coughing is still the same. Also, when he coughs, he sometimes spits up VERY FROATHY type little puddles. Is there anything I can do?
