My 5 month old baby has chills and sweats, but no fever or any other symptons. She is eating normal and seems okay other than;, has cold hands, feet and cheeks, irritable and easily awoken and cries to the point she seems in discomfort. When she does sleep, she wakes up wet from sweat (we are not covering her or swaddling, just in a sleeper). She does not seem as chipper as normal so; we are thinking she is fighting off a bug or maybe constipated as well?
