my 3 years old swallowed super glue around 11 am and were successful to remove most of it from lips and teeth. He was fine and acting normal until 10:30 pm when he woke up with a dry cough and some flame exited his mouth as he was trying to vomit . his temperature is normal. went back to sleep and no more cough for 1 hour. should i take him to the hospital? please advise thank you
