Talk to Pediatrician on Paediatrician

My 4 years old girl vomits each night followed by severe cough after 2 to 3 hrs of sleeping. She is having viral cough also for around 25 days now but it has reduced now but this after sleeping vomit is out of understanding. If it is because of acid reflux issue? Yes she eats her dinner around an hour before bed, does her bed time routine and then i let her walk for a few minutes and then she sleeps.. What should i do
