Hi L.,
I would reccommend that you begin creating the atmosphere that will carry over into the car. First, purchase on Amazon- shipped ASAP (or borrow- or perhaps you already have) a calming CD that she can start listening to at quiet times. I started this when my baby was a new born. During quiet times, nursing times, nap times etc... I would put in a very nice piano CD that I loved as well as she associated with tranquility. (our favorites- Vince Madison (all), Brahms- sleepytime serenade, Enya, Yanni....). Your baby will already be entranced once 3 or 4 settings have been established. You won't believe how easy it will and what a HUGE difference it will make. I think you shoudl try to begin the calming attmosphere association when you can stay home for a couple days in a row (for best and fastest rsults), but if you don't have that luxury, and you have got to do some traveling daily, then start with the same CD in the car. Always start from the beginning until your baby is very familiar with the whole CD, then add in another etc....(but you canot show any reaction to the crying- otherwise, the baby will pick up on it and continue as long as you do. So if is slow starting, try to keep the trips to a minimum. Keep in mind, if whatver you are doing to try to calm the baby while in the car- isn't working, then it doesn't help to continue, try something else. My method is a God-send.
You should know, that this is such a wonderful technique tht applies to gettting the baby ready for the upcoming nap, calming it down when it gets a boo-boo, etc....Babies and children alike like and react best to repetition and familarity. Something they can expect and look for ward to. There really isn't an unexpected surprise for the baby when the music comes on, it is calm because it knows what to expect. So, always keep it in mind (even on your MP3 player in the future)- todler years....imagine - your out shopping for groceries, and the baby is now 2 or 3, having a fit, grouchy, irratable etc....have some headphones (not earbuds) and be prepared with the calming usic that they can't help but to be calmed by.
Another thing that I think will help with those cases that even music cannot fix and the music association has been put in place- visual stimulation....the mirror on the back of the back seat- allows for you to see baby, and for baby to see you. There are toys that keep baby company and busy while on the ride. Interactive kicking, touching, pulling toys that react different ways...they sky is the limit.
But for now- a ritual needs to be created- one that promises the same peaceful music that has already been associated with something else that is calming, naps, nursing, QT in the glider.. etc....
Hope this helps you both relax!
God Bless.
