Hello, my kid is 3 years 1 months, from last 7 days i.e., Feb 14th , he is getting up in the middle of the night and vomiting. before vomiting he is saying yaak yaak and swallows something. I feel like he has mucus in his throat. please advise.. (point to be noted: I have stopped giving boiled and cooled water from Feb 8th as he turns 3 years old)
