Hi - my daughter is almost 2.5. For the past month she has had a bad cough at night. And on about 10 occasions she has vomited. At first the excessive coughing seemed to lead to the vomiting, but last night she vomited twice without too much coughing. No other symptoms. GP has checked her over and found nothing wrong. She’s had a chest x ray which was clear. I assumed it was just a viral chest infection but it has lingered a while now. (she’s been coughing about 6 weeks although vomiting only started a month ago). Has anyone else gone through this and concluded it was something else? She used to have bad reflux as a baby but grew out of it around 8 months. Can reflux suddenly come back in toddlers?! Thanks for any ideas anyone may have!
