My 9 month old has fever no vomiting her poop is very soft like a newborn she is sleeping a lot during the day n not eating as much is this normal?

Fever. She may be sleeping a lot because of dehydration caused by the fever and soft stools. Therefore it is important to give your child electrolyte containing fluids If condition gets worse see your doctor.
No its not normal. Fever is not normal. Since there are no specific symptoms, it is probably a viral illness that has to run its course. Nevertheless, if the fever is high or if it persists your child need to be examined by his/her pediatrician.
No. No, fever at this age could indicate a potentially serious bacterial infection. Specially with decrease eating and increase sleepiness. Take the baby to a dr as soon as possible.
