Did your LO run a fever after the two month vaccinations? My little girl is currently at 100.4. I gave her a little baby tylenol and plan to check it again in about an hour. I didn't call the doctor because the information we have lists 100.4 as the top of the normal range. Also, she's not fussy, her appetite is fine, she's smiley and playful, and doesn't appear to be in pain. I only took her temperature because I noticed her head felt warm while getting her ready for bed.
