What kind of help is needed:
What are some good methods to stop the child from vomiting

Doctor's answer:

When vomiting reoccurs, the first step is to calm the child's emotions and prevent them from crying or screaming loudly. Immediately stop the hidden factors that trigger dry heaves, especially when suspecting an issue with the food. When vomiting reoccurs, avoid any food or drink for one to two hours after dry heaving to allow the gastrointestinal tract to fully rest. If the child is immediately given water or food after dry heaving, it will increase the pressure on the gastrointestinal tract, leading to persistent and severe dry heaving, resulting in further harm.
