Okay ladies... I’m a first time mom with a now month old baby boy. I am terrified of leaving the house with just us two and not being able to see him in the backseat. I was to install a mirror to see him BUT I have a 2018 Buick Encore which sadly doesn’t have a headrest in the middle & the car seat won’t fit on the left or right side (barely fits in the middle) ANDDD I cant use a suction one bc my back glass is too far away😩 sooo i need to somehow rig some on the middle part that can but used as a headrest to attach a mirror to. I have one idea of what I can do but I haven’t tried it out yet.. I NEED HELP!!! Any ideas I’m open to!! Here’s a picture of what the inside of my kind of car looks like

Also a pic of my idea (rope or some kind of strap is the blue)
