Meka does it too
She'll be 2 yrs next month and its always been that way with car rides. Doesnt matter if she's held or in her seat, she shakes on every ride. But, now I've been noticing that she does it when we meet someone, or even if she's waiting for her dinner...she'll shake until its time for her to eat. I try to calm her as well, but it doesn't work. She gets herself so excited. I too wonder, is there anyway to help her get over it or is it just her
