baby getting hurt all the time!!

okay my baby is an early crawler and started around 6 months!! he’s getting super fast now at 8 months and will try to be silly and “run” from you or go up the stairs in our family room(one step)! but in the last week or so he’s started to get hurt at least once a day! obviously not seriously hurt but he’ll skin his knee trying to crawl fast or bump his head on the door frame coming into a room, pull up on the couch or a toy and fall over and bump his head, little things like that. i stay home with him all day and i watch him like a HAWK but still he’s so clumsy and does silly things and ends up hurting himself somehow! i feel like such a bad mom because i’m always right there but he’s so fast it happens in the blink of an eye!! is this normal and when does this stop?? i’m so stressed out because he’ll have scratches and red marks on him and i don’t want people to think i don’t watch him closely 😩
