My little boy had a high fever (101-104) for 4 days straight before he turned 1 years old. I called the Dr on day 2 and they said as long as it wasn't 104 for more than 1 hour and the Tylenol or Motrin didn't make it come down that he was ok, he just needed to drink lots of fluids to stay hydrated.He really had no other symptoms, no ear tugging and he basically was a happy guy although at the peaks of the fever you could tell he was uncomfortable. He wanted a little more TLC than my usually busy bee. Look for other symptoms though, if your child is extremely sleepy and lethargic or if they are very uncomfortable its time to call the Dr again. They also told me if he still had a fever on day 4 call them. He did so I ended up taking him in. They did a urine analysis and blood work to test for internal infections. He tested fine and they sent me home. His fever broke later on that night and he was fine. Just turned out to be a virus. On the other hand, you know your child best and if something seems a little off to you take him! Don't wait. Here is an article I found on BabyCenter.com that I use as a guide. I hope this helps!!
****The BabyCenter Seven: Signs it's something serious****
When would our panel of pediatricians want you to give them a call? If your sick child showed any of the following signs that he's not just suffering from a run-of-the-mill cold or flu:
1. High fever. Be on the lookout for fever 99 degrees Fahrenheit or higher in infants under 2 months, 101 degrees or higher in children 2 months to 2 years old, and 104 degrees or higher in kids over 2. These high temperatures could mean an infection or other medical problem that needs immediate attention.
2. Symptoms getting worse, not better, after seven to ten days. Going downhill suggests that a cold virus has evolved into a bacterial infection, such as a sinus infection, that requires antibiotics.
3. Lethargy. Extreme sluggishness can be a red flag for conditions needing medical attention. Call the doctor if your baby won't wake up to feed or can't be aroused by prodding or loud noises, or if your older child can't haul herself out of bed and hardly responds to food, your voice, your touch, loud noises, or bright lights.
4. Persistent vomiting. If your child can't keep anything down — not even sips of water — or isn't peeing for an entire day, he could be getting seriously dehydrated.
5. Stiff neck. It might just be a pulled muscle, but if your child is already sick and can't touch her chin to her chest, it could be a sign of meningitis or another serious infection. (If your child has a stiff neck with no other signs of illness — such as fever, vomiting, or a rash — it's reasonable to try some ibuprofen and see if it gets better.)
6. Mucus that starts out clear, but turns green. Sometimes colds cause thick, green mucus right from the start — and that's nothing to worry about. But if the mucus starts out clear and changes after seven to ten days to the nasty green stuff — especially if new symptoms like a fever, headache, or cough suddenly appear — that's a sign of bacterial infection and the need for antibiotics.
7. Any symptoms at all in a baby under 3 months. Fever, diarrhea, vomiting, persistent fussiness, poor feeding, cough, and runny nose are all things your newborn's doctor should hear about pronto.
