Baby feeding herself.

My baby is 8 months old. She has always refused a dummy and teethers and therefore doesn’t put food in her mouth. She has just started letting me spoon feed her but when I give her finger food or a spoon she just throws it on the floor as she’s not used to putting anything in her mouth herself. I’m getting worried as she’s 8 months now and not showing signs of feeding herself. Anyone else’s baby the same? Should I be worried?
