Hi Ashely,
First check if she's teething. Is she drooling a lot? Biting a lot on hard things? If so, this is normal for babies to run fevers like she is with teething involved. If not, it could be an ear infection. That's also common with babies. Does she show signs of discomfort other than fever, like lethargy,or long periods of fussiness? Or does she seem responsive and alert when she's awake? Try some Motrin for her. See if that will bring down her temp. Also put a cool wash cloth on her little head to help the temp go down. Another clue to an ear infection is if she's pulling, or tugging at her ear constantly. You'll need to see the doc if she shows signs of this. Also, I did some research on your medicines, and with the AUGMENTIN, and AMOXICILLIN, there are "infrequent side effects" that includes breathing problems. Omnicef didn't have breathing problems listed in their side effects. So, with that said, this is probably where your baby was getting her troubles in breathing. Now, did you finish the Omnicef as directed by the doctor? It's imperative that you always finish doses given by the doctor, (when it comes to antibiotics), to completely get rid of the illness. If you don't, you have a chance of getting a relapse. If your baby isn't showing signs physically, of illness, and just has a fever, I would make a good guess it's teething. Try getting her temp down using the suggestions I gave, and if she is still running a fever and it doesn't break withing 12 hours, call your doctor. You can also call anyway and talk with the nurse about your concerns and they can evaluate from what you say, if the baby needs to come in, or she can give you advice on what to do. My Mom also said that children will run a fever with no signs of being sick, and then in a couple of days, it will break. I know this because my son just went thru that.
Also, there was a flu bug that was going around that was affecting people pretty badly. Since your baby already got some antibiotics, she may not get it again. Are you bundling your little one up too warmly? It was about 81 degrees outside today. Warm enough for pants, or shorts, and a short sleeve top. If you dressed your child up too warmly when it's hot outside, then chances are she will spike a temp..just from body heat. I know after children get their immunizations, they will spike a temp also,but only for a short period. I hope my suggestions helped you. Let me know how she's doing. Best wishes, G.
