Baby Doesn't like Babywearing... help!

My baby seems to seriously hate being in the wrap... he is two months. I've done both the newborn hold (legs in) and I think it's called the hug hold (with his legs out). I'm also worried he might be too little for legs out, but he's not a tiny baby by any means. His biggest problem is that he starts flailing and he head butts me HARD. If I forget that I have a necklace on, that makes it just that much more painful for him. ?
