Not sitting up!!

Is anyone’s baby not sitting up yet?? My little guy turned 8 months on the 31st but is not sitting up yet. He sits down on my lap just fine but if I go to sit him on the floor he stiffens his legs and throws himself back.

Is there anyway to help him sit up or is it just something that will happen eventually?
