My kitten keeps on bumping into things! And he attacks me a lot !

So my kitten is a Scottish fold (Leo) and he plays a lot and he always seem to hit a body part to something, for example today i was playing with him and he walked back and bumped his head on the chair (but he didn't meow) so i don't think that it was realllllly hard but still. Im scared that one day when he will hit his head and it will hurt hime like a head conclusion or break a bone . 

Attack:

So my kitten (Leo) always seems to attack my legs but i know he is playing but i don't know why he always attacks me. its getting really annoying and I'm starting to get scared of him  . i need some help 

Any chance he has cross eyes? My cat did that when she was younger and I didn't think much about it (other than maybe she is not too smart). Many years later, I had a different vet who asked me if she can walk properly, as her one eye is pretty crossed. 

My kitten does the exact same thing, both bumping into things and attacking my legs.
From what I've read, it's just their age. They're goofy and uncoordinated so they don't really notice they're surrounded by objects that they can hit. Most kitties grow out of this clumsiness.
For the attacking legs, again the age, anything that moves is prey to them. My little lady doesn't listen to anything but the water bottle, I have a squirt bottle that I carry and spray her butt and loudly say "no", every time she attacks my legs. You may be able to do something less "harsh" if he isn't as stubborn as mine is, but regardless it's important to stop this behavior while they're little because it'll hurt a lot worse when they're older.

My kitten is a Himalayan! You should post some pictures of your baby!

Hi,

Thanks for answering my question,

Bumping:

Well I guess about the bumping into objects is because of his age because he is still a kitten, but I'm still scared that he will hit his head or leg hard and it will hurt him.

Attacking:

When he attacks my legs a say "shhht no"  but that seems to grab his attention and he does stop what he is doing and goes to  play with something else 

I'll try to post some pictures of him!!
