I know toddlers fall a lot but does this bruising seem excessive?

My 17 month old has been walking (and falling, lol) for about 8 months. He always has a couple little bruises but lately I’ve been noticing his legs are really banged up.

FTM and just don’t know if this is normal. He’s definitely doing it to himself, falling or banging against things. Doesn’t seem bothered or hurt, just making mommy worry.
