Question:

My two-year-old child (weighing 10 kg) has a temperature of 38°C (100.4°F) in both ears, but their toes feel cold. Usually, with a fever, the toes should be warm, but they are cold right now. Should I give them a fever reducer? I have been observing my child for about 40 minutes, but the temperature is not dropping and is actually rising slightly. For context, my child's normal basal body temperature is generally a bit high, around 37.1°C to 37.3°C (98.8°F to 99.1°F).

Answer:

Dealing with a two-year-old's fever can be stressful, and you have done a great job monitoring your child so carefully.

【What to Do Now】

• If your child's temperature is 38°C (100.4°F) and they look uncomfortable, you can safely give them a fever reducer.

• Acetaminophen: For a 10 kg child, the typical dose is 100 to 150 mg. Always check the medication label to calculate the exact amount (for a standard 160 mg/5 mL liquid concentration, this is about 3 to 4.5 mL).

• It can be given every 4 to 6 hours, up to a maximum of 5 times a day.

• Dress your child in light clothing and keep the room at a comfortable temperature.

• Offer fluids (water, breast milk, or formula) frequently in small amounts to prevent dehydration.

【Why the Hands and Feet Are Cold】

In the early stages of a fever as the body's temperature is rising, blood vessels in the extremities constrict. This can cause the hands and feet to feel cold while the trunk (chest and back) feels hot. As long as your child is not experiencing severe chills (uncontrollable shivering) and their lip color is normal, this is a completely normal and temporary phenomenon.

【Warning Signs — Seek Medical Attention Immediately If:】

• The lips or fingernails turn blue, or the child is experiencing shortness of breath.

• The child is extremely lethargic, limp, or unable to make eye contact.

• There has been no urine output for more than 8 hours.

• The fever lasts for more than 3 days or continues to worsen.

• The fever is accompanied by a new rash, stiff neck, or repeated vomiting.

If you are unsure or if the fever does not respond to medication, contact your pediatrician for further guidance. If it is after hours, weekends, or a holiday, please take your child to a local urgent care clinic or emergency room for a proper in-person evaluation.
