Couch Gaming setups

So I switch between playing games from my desk and my couch. I have a long HDMI cable that runs from my desktop to my tv. before I would use a bluetooth keyboard and a bluetooth mouse when playing from the couch with a little table or with a xbox 360 controller.

recently we had a baby and she sleeps a bit less now but still for a few hours at a time during the day. now I feed her and she will fall asleep on me so sometimes I dont really want to move much after she falls asleep but I got pretty into farthest frontier which needs a keyboard and mouse to play. but with baby on my chest I cant really use the desk and a keyboard and mouse is kind of tough to use, the mouse likes to slide around which scrolls the view

I started looking up solutions and ended up finding the elecom relacon trackball mouse

I just got it today and was playing a bit of elder scrolls oblivion with it and it works pretty well

on my left hand I am using my quefrency split keyboard half

which isnt bad but then I found the Azeron cyborg after going down a rabbit hole on gaming keypads like the razer tartarus and logitech g13. I watched a few youtube videos and the idea of the thumb stick sounded very good for movement so I was sold on the azeron. Im excited to try it and believe that is the best to use for my left hand.

I found a promising looking gyro mouse from some guys but there hasnt been any updates on the project

I would like somthing like a joycon mixed with a steam touch controller but i cant find anything. is anyone using any strange gaming methods like this? that has found something that works well
