My 20 month old son keeps falling asleep then throwing up multiple times of when hes sleeping, sometimes only once. Accrues during his nap time and bed time . When he throws up he is sleeping, sometimes awake, when he is done he passes out in a deep sleep. I took him to the doctors she thought it was his appendix so I got blood work and x-rays done, they came up fine nothing wrong. He doesn t want to eat he drinks a little and hes losing alot of weight.
