Thanks for writing to health care magic.
If a baby is has vomiting
then that should be continued by antiemetics. If those vomiting cannot be supressed by antiemetic then one should administer intravenous fluids to prevent dehydration
If vomiting are not controlled then dehydration will result and so give antiemetics to control them as prescribed by your doctor.
please monitor your kid for signs of dehydration.
1. Decreased skin turgor
2. Increasing thirst.
3. Sunken eyes.
6. Decreasing passage of urine.
Hope this helps
