Warmies??? For the car

So I've seen the ads for warmies. A lavender infused microwaveable stuffed animal for children of all ages (their advertising not my words) obviously this is not nessisarily a safe item for ALL ages since babies cannot sleep with them. But my 2mo HATES the car I mean screams like crazy. My first was like this and I rode in the back with him and that helped but now woth 3 kids I cannot ride in the back to console my daughter. I was wondering if anyone had these. I was thinking of using it for its lavender scent and slight weight across her legs to comfort her with close observation of course to be sure she doesnt pull it out of place. Also i would 100% love some product recommendations that helped your little ones in the car.
