Change table help

Ka

Y'all my son won't stop rolling over on the change table so I do all changes on the floor and pin him down with my legs. I've tried toys to distract him, giving him a clean diaper to hold, singing, soother, I dunno what else to do! I'm considering hanging a mobile but I can't even find any that are connected to a stand since it's on a dresser so I may need to make something.

Anyone have tips?
