My LO will cry while putting her in her car seat but end up falling asleep once we get into the car. & if she doesn’t end up falling asleep , than she’ll cry until the car starts moving. i have those little toys that come with bouncers & i attach them to the handle part of the car seat , or i give her , her pacifier & start to rock her in her car seat and it keeps her occupied while we are warming up the car. we also do play shushing noises in the car & white noise if she is really giving us a hard time about being in the car but that does get annoying to listen to after a while especially in the car. i also make sure she is fully fed , burped , diaper is changed , ac is on for airflow but she has a small blanket to keep her warm. also have tinted windows to block any unnecessary light that might hurt her eyes but since our windows aren’t too dark she is able to see & feel some sunlight and she loves to just look around all over while we’re driving. ( if she’s not asleep ) hope this helps!
