Question:
Both of my children are vomiting. My 3-year-old threw up from 7 PM to 9 PM, then fell asleep exhausted. My 11-month-old started vomiting around 8 PM and is still throwing up clear, mucus-like fluid even while sleeping in my arms.
What should I do? There is no emergency room nearby, so I am wondering if I should monitor them at home and go to the pediatrician in the morning for IV fluids. If they wake up, should I try to give them some water?
My family suggests waiting until morning, but they look so exhausted that I am really worried something worse might happen. They have both vomited about 10 times. My older child hasn't urinated in about 5 hours, and my younger one last urinated around 6 PM. For food, they had an apple for lunch and rice with seaweed for dinner.
Answer:
It must be incredibly worrying to have both of your children vomiting at the same time. I understand you must feel even more anxious since there is no emergency room nearby tonight.
[Current Situation Assessment]
• Older child (3.5 years old): Vomited for 2 hours and fell asleep exhausted.
• Younger child (11 months old): Continues to vomit, bringing up only clear, mucus-like fluid.
• Both children have vomited more than 10 times.
⚠️ Urgent Things to Check:
1. Has your 11-month-old gone without urinating for over 8 hours?
2. Are their lips dry, or do their eyes look sunken?
3. Do they produce tears when they cry?
[What You Should Do Immediately]
1. Younger child (11 months old) - Requires extra attention:
• Give 1-2 spoons of water or breast milk slowly every 5-10 minutes.
• If they vomit, wait 5 minutes before trying again.
• If the baby constantly wants to be held and appears unusually lethargic, it could be a sign of dehydration.
2. Older child (3.5 years old):
• Monitor their breathing while they sleep (watch their chest rise and fall).
• If they wake up, give water little by little (one small sip at a time).
[When to Go to the Emergency Room]
→ Go Immediately: If there is no urination for over 8 hours, continuous extreme lethargy, or no tears when crying.
→ Leave Even During the Night: If the vomiting persists and they cannot keep any fluids down at all.
Rather than waiting until morning, it is safer to go to a hospital right now if you are highly concerned about your 11-month-old's condition. Dehydration can progress very quickly, especially in infants around 11 months of age.
