I think there's a possibility that there's something in the neck that can cause coughing, throataches and shortness of breath, and the baby can vomit more often, and it's best to come to the hospital as soon as possible to prevent further complications.
Doctor, there's been a lot of coughing and throataches these days, and a lot of saliva in the baby, and sometimes it's pretty, it's swollen with lymph nodes.
