Wen I got home I took a underarm temp and it came back 99.3 it's now 8 o'clock and I took a rectal temp and it was 102.1 he hasn't ate much today because they said he couldn't breath and eat at the same time   I'm calling his doctor in the morning but I just want to make sure he'll be fine till the morning
