is this an attachment issue?

my 6 yr old, when he falls or hurts himself (not serious) and when i go see if he is ok, he gets mad at me and says "leave me alone"

my child does have attachment issues, but sometimes i dont know if its an attachment issue, or if its like most 6 yr old boys, kinda doing the independent thing.

For the more serious injuries, like falling off his bike where he really hurts himself, he has let me hold him and comfort him.

what do people think? if it is an attachment issue, what should i do, i usually just stand there and tell him that i just wanted to see if he is ok. Then he says "hes fine" and gets up and continues on playing.

any thoughts
