Fall 6 times in 11 month old LO

I feel so useless as a mom. My son who is 10 month old has fallen 6 times in his life.. 5 times fall from queen size bed and 1 time fall down from high chair at dining room.. 6 times fall on his head.. 6 times fall on hard floor.. kitchen is those hard tiles.. I observed 48hrs to see symptoms.. so far nothing.. but I still feel mom guilty and my mine keep thinking if there any internal injury or bleed..#advicepls
