Baby crying at my every time I sit down?

I play with him and walk with him but the SECOND I try to sit on the couch and just take a break he goes over and starts freaking out, I’m pregnant and tired all the time right now but I still put in the effort to stimulate and play with him.

I feel like all he does is yell at me for everything now, but especially this. Is anyone else’s baby acting this way?
