Our son just turned 2 in May. Today we played outside for about 20 minutes and ever since he has had a fever. We have given ibuprofen twice, each time it will bring down the temp. The highest it got was 103.5, after the 2nd dose of medicine, it went down to 101.4 and now it is back up to 102.2 climbing again. Should we take him to the ER for possible heat stroke? He has a rapid heart rate, was holding his head (possible headache). He is keeping fluids down, mouth is wet w/ saliva and drool, and still has wet diapers. We also gave cool bath, and placed washcloths on forehead, back and in between legs to keep him cool.
