felecia187 i have no idea how this works so here goes , you are driving along and you child is in the car seat in the back seat , your kids crying yelling , and maybe making you a little upset also , well i have no idea why this works , but it dose , so here is what you do throw a light blanked over the whole car seat with your kid in it , make sure the child can get lots of air , now what will happen believe me or not the child will indeed fall fast asleep i kid you not , this has worked for me many a time , no it won't work on teenagers we only wish , so the next time your child is stressing you out try this and get your peace of mind back , enjoy
