Help Me With Swingset 2x6 Span

[pelphrey]

I am by no means a carpenter!!!! I started this project on the 4th, between gathering all of the material needed and the random storms that would roll in I feel like I got a lot done.

My question is... The 2x6 span I have coming off has some left/right wobble to it. I know I can cut it down some, but will that help? Can I bolt another 2x6 to the backside of it and expect the swaying to stop? I probably should have used a 4x4, 94% of this I did on my own.

For those interested. Here is some more photo's

i'd sister up that 2x6 and also add another 2x6 piece going to the face.
kinda like the really bad top down view i sketched.......

Thanks @link81

I got some more work. Added a 2x6 behind the original! It’s a lot more sturdy! Next up is the piece from the back to front if I see more sway!
