Today SO and I were doing lots of yard work, dd would spend an hour or so outside then i would bring her in for an hour because it was so hot. she was in her pack n play under and tree and a beach umbrella. I frequently checked to make sure NO sun was peaking through... it got up to about 85. she has been in just a diaper all day. eating fine, plenty of wet diapers... she felt really warm when i brought her in and checked her rectal and it was 100.3. I know that isnt anything crazy but after talking to my mother she made it sound like i had her outside too long.... she has been drooling but i would hate to put it off as that if it could be something more serious.
