So my bubs used to LOVE car rides. I'd put him in his car seat, he'd be all giggly and would fall asleep right when we started moving. I always made sure he was fed, changed and dressed appropriately....but these past few car rides, if I went thru a drive thru where we stopped completely...he starts screaming bloody murder. I have car toys (always change them out) and have his favorite songs playing but nothing seems to calm him down until we start moving again. How can I get him used to stop and go. If I'm doing grocery pickup or just grabbing a simple drink, its now a stressful situation. He is now 8 weeks and has loved car rides up until last week. Any suggestions?
