99.5 temp in 5 1/2 week old

So yesterday I notice that DD had a bit phlegm. She usually wakes up with some and it goes away but yesterday it stayed the entire day. She then threw up (alot) of the BM that I fed her but after her bath and an additional nursing, she went to bed.

This morning at 4am, she woke for her nursing and I noticed that she felt warm. She also had a stuffy nose. When I first took it, it cam in at 100.2. I undressed her and put her in lighter clothes to let her skin breathe a bit before taking her temp again.
It came in at 99.5, which the thermometer is telling me is normal. I took it three more times and it all showed temps in the low 99's. These were rectal temps.

DH is at work and expected to come home at 10am. I have a call into the ped's office. I know I have seen posts saying that temps in an infant mean possible spinal taps. I could be paranoid but am starting to worry.

my dr. always said a fever isnt a fever in any age baby until it reaches 100.4

if your worried call your dr.

me personally would not worry.

and spinals are done for newborns with fevers, if its high... i think over 102

Re: 99.5 temp in 5 1/2 week old

Anything over 100.4 is cause for concern, under that is considered normal.
