Any tips to get two year old to stop using my pregnant belly as leverage to get up?

I try to tell her (every time she does it) that it hurts mommy and pushes on the baby (and is not comfortable) but she still uses my lower stomach to push herself up from the couch and ugh 😩 She has an older brother, is very verbal and very much understands most of what we tell her. This one she just can not get. I’m already uncomfortable and when she pushes, it kicks up my nausea.
