housebound during weekends!

Alka
My girl doesnt like to be on car seat and dont feel asleep on stroller or her car seat.
Sometimes, we have to stop the car and make her sleep :). She likes observibg the trees n objects through the car window which is good in some sense but we cannot think of planning to spend weekends and outings. Any suggestions to make her sleep during road trips?? I tries putting on soothing music already...
