Ok ladies. I'm having trouble committing to buying a sun shade for our cars...but we are putting DS in his convertible car seat here really soon and I just cannot pull the trigger. So in your experience, do you have a kind/brand you like...the kind that hook over the top of your window, the kind with suction cups or the ones that cling right to the glass? Help! There are so many kinds and I don't want to be cussing it out every day because if falls down constantly!
