Hello...I don't think you are being overly concerned, a temp that high is cause for concern. I read that a temp of 104 for more than 5 days is unhealthy and you should be taken to the emergency room. Any normal Mom would take their child way before then although it is not necessary. Having a temp of 103 to 105 for a day and a half isn't long enough to have a long term effect down the road. If you are concerned about her CBC count, it won't hurt to question your Dr. to see if a test is necessary. My healthcare provider has a medical advice hotline and I use it for any and every little question I have...that's what it is there for. And since you pay your Dr. you should be able to ask any question about anything at any time. Exercise that right!!
