Yesterday morning, my 10 month old had an endoscopy and flex sig. Since then, she has be unable to sleep, incredibly snotty/congested, and refusing to take a bottle. The few bottles she has taken, she has vomited, because her throat is bothering her so badly that she is gagging and making herself vomit. How long is a sore throat to be expected? Is the snotty nose and congestion normal?
