Good morning! Need help, the child has been eating for two days now, takes 2-3 sips and starts crying. As a result, hungry but refuses, so may not sleep well. (On IV, goes to the toilet once every two days, nothing bothered him before). We'll go to the doctor, but it will take a lot of time to get there and we may not make it on time.
