Question:
My 22-month-old toddler has been vomiting since 6 PM, about 5 times in total. They threw up everything they ate for lunch. Afterward, they asked for water, but after drinking it, they threw up three more times. They do not have a fever, but their hands and feet feel hot. My child cried because they were startled and is now sleeping, but they constantly want to be held. Should we go to the emergency room tonight if their diaper stays dry, or is it safe to wait and see the pediatrician tomorrow morning?
Answer:
It is completely understandable that you are worried after seeing your toddler vomit so frequently.
Here is an assessment of the current situation:
* Vomiting multiple times (including water): This indicates a high risk of dehydration.
* Hot hands and feet: This suggests that you should regularly recheck their temperature.
* Wanting to be held: This is a clear sign that your child is feeling uncomfortable and unwell.
What to Do Right Now:
1. Wait for about 30 minutes after the last vomiting episode, then wake them slightly to offer just 1 to 2 sips of water. Do not give a large amount at once.
2. Check their diaper and write down the exact time of their last urination.
3. Check their temperature again.
4. If they successfully keep the small sips of water down without vomiting, gradually increase the amount of water given every 10 minutes.
When to Go to the Emergency Room Immediately (Even Overnight):
* There has been no wet diaper for 8 hours or more.
* You notice signs of dehydration, such as dry lips or crying without tears.
* Your child appears severely lethargic, unresponsive, or is very difficult to wake up.
* Vomiting is persistent, they cannot keep any water down, or they vomit bile (yellow or green fluid).
If your child can successfully keep small amounts of water down and eventually urinates, it is generally safe to wait and visit your pediatrician tomorrow morning. For now, focusing on frequent, small amounts of hydration is the most important step. However, please seek immediate in-person medical evaluation at the ER if any of the warning signs mentioned above occur.
