My dd is 12 weeks old and we are having a real problem with the car seat. She is normally a happy chilled out baby but as soon as she goes in the car seat she becomes hysterical-screaming non stop til I pick her up where she stops crying immediately. It's not that she doesn't like being put down as she's happy in the bouncer, play gym etc. I tried making it cooler/ warmer in the car, had someone sat next to her tring to distract her but nothing works! It is making driving anywhere a stressful experience and I hate hearing her do upset and not being able to do anything about it!! Any suggestions?!
