My 3 year old had fever on 31 august that lasted for 3 days , then she had fever again on 8th September that lasted for two days, now from 17th she has slight fever every now and then(99.9-100.3). On 19th she had fever again after 24hr .. should i get her checked for something? She also had febrile seizure twice before she was 2 year old. I give her 4ml crocin after every 5 hr for fever but it just comes back after 8 days . And its been 3 days her condition improves and then suddenly she gets high fever at night . What do i do
