Thanks for your query.
symptoms are suggestive of gastroenteritis
.as your daughter is feeling thirsty so she is having dehydration
,so i advise you to give oral rehydration solution sip by sip,give her water,coconut water,curd,banana.if temperature goes beyond 100 give paracetamol
.in case symptoms do not subside,she becomes more lethargic then take her to pediatrician
Your daughter will be fine
